Detailed Description

groups Representation of a group of SBML components.

The Group class is the first and most central class in the SBML Level 3 Groups package. This class represents a group of entities: a simple mechanism for indicating that particular components of an SBML model are related in some way. The nature of the relationship is left up to the modeler, and can be clarified by means of annotations on model components. Groups may contain either the same or different types of SBML objects, and groups may be nested if desired. There are no predefined modeling or mathematical semantics associated with groups.

The Groups class has one required attribute, 'kind'; two optional attributes, 'id' and 'name'; and a single child element, ListOfMembers. The membership of a group is determined by the contents of the list of members stored in Member objects within the ListOfMembers child of a Group object. Since the Group class of objects is derived from SBase, and SBase provides the ability to attach SBO terms as well as MIRIAM annotations, the semantics of a given group in a model can be made more precise using references to external controlled vocabularies and ontologies.

Group kinds

The attribute 'kind' on Group is used to indicate the nature of the group defined by a Group instance. The 'kind' attribute must always have one of the following three possible values:

  • 'classification': The group represents a class, and its members have an is-a relationship to the group. For example, the group could represent a type of molecule such as ATP, and the members could be species located in different compartments, thereby establishing that the species are pools of the same molecule in different locations.
  • 'partonomy': The group represents a collection of parts, and its members have a part-of relationship to the group. For example, the group could represent a cellular structure, and individual compartments could be made members of the group to indicate they represent subparts of that cellular structure.
  • 'collection': The grouping is merely a collection for convenience, without an implied relationship between the members. For example, the group could be used to collect together multiple disparate components of a model—species, reactions, events—involved in a particular phenotype, and apply a common annotation rather than having to copy the same annotation to each component individually.

In the libSBML API for Groups, these possible values for the 'kind' attribute are programmatically represented as constants so that callers will not normally need to deal with text string values. The following are the constants defined for the three values of 'kind' (plus an additional constant to represent unrecognized values):

Groups and their members

If an SBML element is referenced by a Group's child Member (directly or indirectly), it is considered to be a member of that Group. If the same element is referenced by multiple Member objects, this is equivalent to including it just once. (It is considered best practice to avoid this, but does not make for an invalid SBML document.)

Children of referenced elements are not considered to be members of the Group: a KineticLaw of a referenced Reaction is not itself a Group member. Even the membership of so-called SBML container classes (e.g., ListOfSpecies, ListOfCompartments, etc.) does not imply inclusion of children as members of the Group. The sole exception to this rule is the handling of ListOfMembers class, described below.

Semantics of group memberships

If a Member object within a Group object's ListOfMembers references another Group object, it is the referenced Group itself that is considered to be a member of the parent Group, not the corresponding referenced model component(s). This is true regardless of whether those components themselves happen to point to other components using some mechanism defined by another SBML Level 3 package (as happens, for example, in the SBML Level 3 Hierarchical Model Composition package and its use of SBaseRef). However, if instead a Member object references a ListOfMembers object (using the 'id' attribute permitted on ListOfMembers objects), it is the components of that ListOfMembers that are considered to be part of the parent Group. In other words: if in some Group G, a Member M references another Group, that Group is the member of G; if M references a ListOfMembers, it is the entities referenced by the Member objects within the ListOfMembers that are the members of G and not the ListOfMembers object itself.

The implication of this is that any rule that applies to members of a group (such the meaning of the 'kind' attribute, or the restrictions on the application of 'sboTerm' attributes on a ListOfMembers) applies to the child group when referenced by the Group 'id', and to the members of the child group when referenced by the ListOfMembers 'id'. In an example situation where a parent group includes two Species plus a Group which itself contains three other Species, if the parent group's ListOfMembers is given an 'sboTerm' attribute value, that SBO term applies to the two species and the group, not to the three child species members of the second group. (Note also that in such a case, the parent group's 'kind' attribute value would almost certainly be 'collection' or 'partonomy', and not 'classification', as two species and a group are very unlikely to be classified as the same thing.) In contrast, in the situation where a parent group includes two Species plus a ListOfMembers which contains three other Species, the parent group's ListOfMembers 'sboTerm' would apply to the five Species, and could be more reasonably marked as a 'classification'.

In a future version of this SBML Level 3 Groups specification, it may be possible to perform set operations on groups, but for now, this type of union is the only set operation that is possible.

Groups are not permitted to be circular: no Member may reference itself, its parent ListOfMembers, nor its parent Group. If a Member references a Group, the same restrictions apply to that subgroup's children: they may not reference the Member, its parent ListOfMembers, nor its parent Group, and if any of those children reference a Group, the same restrictions apply to them, etc.

If a Member has a 'idRef' or 'metaIdRef' attribute which references an object from a namespace that is not understood by the interpreter of the SBML model, that Member must be ignored. The referenced object will not be understood by the interpreter, and therefore has no need to become a member of the group. If an interpreter cannot tell whether a referenced object does not exist or if exists in an unparsed namespace, it may choose to produce a warning.

Constructor & Destructor Documentation

def libsbml.Group.__init__ (   self,
  args 
)

This method has multiple variants; they differ in the arguments they accept.

__init__(long  level, long  version, long  pkgVersion)   Group
__init__(long  level, long  version)   Group
__init__(long  level)   Group
__init__()   Group
__init__(GroupsPkgNamespaces groupsns)   Group
__init__(Group orig)   Group

Each variant is described separately below.


Method variant with the following signature:
Group(Group orig)

Copy constructor for Group.

Parameters
origthe Group instance to copy.

Method variant with the following signature:
Group(long level = GroupsExtension.getDefaultLevel(), long version = GroupsExtension.getDefaultVersion(), long pkgVersion = GroupsExtension.getDefaultPackageVersion())

Creates a new Group using the given SBML Level, Version and “groups” package version.

Parameters
levela long integer, the SBML Level to assign to this Group.
versiona long integer, the SBML Version to assign to this Group.
pkgVersiona long integer, the SBML Groups Version to assign to this Group.
Note
Attempting to add an object to an SBMLDocument having a different combination of SBML Level, Version and XML namespaces than the object itself will result in an error at the time a caller attempts to make the addition. A parent object must have compatible Level, Version and XML namespaces. (Strictly speaking, a parent may also have more XML namespaces than a child, but the reverse is not permitted.) The restriction is necessary to ensure that an SBML model has a consistent overall structure. This requires callers to manage their objects carefully, but the benefit is increased flexibility in how models can be created by permitting callers to create objects bottom-up if desired. In situations where objects are not yet attached to parents (e.g., SBMLDocument), knowledge of the intented SBML Level and Version help libSBML determine such things as whether it is valid to assign a particular value to an attribute. For packages, this means that the parent object to which this package element is being added must have been created with the package namespace, or that the package namespace was added to it, even if that parent is not a package object itself.
Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value. This is not to be intepreted as a Python keyword argument; the use of a parameter name followed by an equals sign followed by a value is only meant to indicate a default value if the argument is not provided at all. It is not a keyword in the Python sense.

Method variant with the following signature:
Group(GroupsPkgNamespaces groupsns)

Creates a new Group using the given GroupsPkgNamespaces object.

The package namespaces object used in this constructor is derived from a SBMLNamespaces object, which encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and package version and name information used in addition to SBML Level 3 Core. A common approach to using libSBML's SBMLNamespaces facilities is to create an package namespace object somewhere in a program once, then hand that object as needed to object constructors of that package that accept it as and argument, such as this one.
Parameters
groupsnsthe GroupsPkgNamespaces object.
Note
Attempting to add an object to an SBMLDocument having a different combination of SBML Level, Version and XML namespaces than the object itself will result in an error at the time a caller attempts to make the addition. A parent object must have compatible Level, Version and XML namespaces. (Strictly speaking, a parent may also have more XML namespaces than a child, but the reverse is not permitted.)

In situations where objects are not yet attached to parents (e.g., SBMLDocument), knowledge of the intented SBML Level and Version help libSBML determine such things as whether it is valid to assign a particular value to an attribute. For packages, this means that the parent object to which this package element is being added must have been created with the package namespace, or that the package namespace was added to it, even if that parent is not a package object itself.

Member Function Documentation

def libsbml.SBase.addCVTerm (   self,
  term,
  newBag = False 
)
inherited

Adds a copy of the given CVTerm object to this SBML object.

addCVTerm(CVTerm term, bool newBag)   int
addCVTerm(CVTerm term)   int
Parameters
termthe CVTerm to assign.
newBagif True, creates a new RDF bag with the same identifier as a previous bag, and if False, adds the term to an existing RDF bag with the same type of qualifier as the term being added.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
Since the CV Term uses the 'metaid' attribute of the object as a reference, if the object has no 'metaid' attribute value set, then the CVTerm will not be added.
This method should be used with some caution. The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained inside this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance in this object. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result. Please see other methods on this class (particularly a corresponding method whose name begins with the word create) for alternatives that do not lead to these issues.

def libsbml.SBase.appendAnnotation (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

appendAnnotation(XMLNode annotation)   int
appendAnnotation(string annotation)   int

Each variant is described separately below.


Method variant with the following signature:
appendAnnotation(XMLNode annotation)

Appends the given annotation to the 'annotation' subelement of this object.

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Unlike SBase.setAnnotation() or SBase.setAnnotation(), this method allows other annotations to be preserved when an application adds its own data.

Parameters
annotationan XML structure that is to be copied and appended to the content of the 'annotation' subelement of this object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.SBase.appendNotes (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

appendNotes(XMLNode notes)   int
appendNotes(string notes)   int

Each variant is described separately below.


Method variant with the following signature:
appendNotes(string notes)

Appends the given notes to the 'notes' subelement of this object.

The content of the parameter notes is copied.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

Parameters
notesan XML string that is to appended to the content of the 'notes' subelement of this object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.SBase.deleteDisabledPlugins (   self,

)
inherited

Deletes all information stored in disabled plugins.

deleteDisabledPlugins(bool recursive)
deleteDisabledPlugins()

If the plugin is re-enabled later, it will then not have any previously-stored information.

SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.
If a plugin is disabled, the package information it contains is no longer considered to be part of the SBML document for the purposes of searching the document or writing out the document. However, the information is still retained, so if the plugin is enabled again, the same information will once again be available, and will be written out to the final model.
Parameters
recursiveif True, the disabled information will be deleted also from all child elements, otherwise only from this SBase element.

def libsbml.SBase.disablePackage (   self,
  pkgURI,
  pkgPrefix 
)
inherited

Disables the given SBML Level 3 package on this object.

disablePackage(string pkgURI, string pkgPrefix)   int

This method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.

An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from an other SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:

1 import sys
2 import os.path
3 from libsbml import *
4 
5 # We read an SBML L3V1 model that uses the 'comp' package.
6 
7 doc = readSBML('sbml-file-with-comp-elements.xml');
8 if doc.getNumErrors() > 0:
9  print('readSBML encountered errors while reading the file.')
10  doc.printErrors()
11  sys.exit(1)
12 
13 # We extract one of the species from the model.
14 
15 model = doc.getModel()
16 if model == None:
17  print('Unable to retrieve Model object')
18  sys.exit(1)
19 
20 s1 = model.getSpecies(0)
21 if s1 == None:
22  print('Unable to retrieve Species object')
23  sys.exit(1)
24 
25 # We construct a new model.
26 # This model does not use the 'comp' package.
27 
28 try:
29  newDoc = SBMLDocument(3, 1)
30 except ValueError:
31  print('Could not create SBMLDocument object')
32  sys.exit(1)
33 
34 newModel = newDoc.createModel()
35 if newModel == None:
36  print('Unable to create new Model object')
37  sys.exit(1)
38 
39 # The following would normally fail with an error, because
40 # addSpecies() would first check that the parent of the given
41 # object has namespaces declared, and will discover that s1
42 # does but newModel does not.
43 
44 # newModel.addSpecies(s1)
45 
46 # However, if we disable the 'comp' package on s1, then the
47 # call to addSpecies will work.
48 
49 compNS = 'http://www.sbml.org/sbml/level3/version1/comp/version1'
50 status = s1.disablePackage(compNS, 'comp')
51 if status != LIBSBML_OPERATION_SUCCESS:
52  print('Unable to disable package.')
53  sys.exit(1)
54 
55 newSpecies = newModel.addSpecies(s1) # This will work now.
56 if newSpecies == None:
57  print('Could not add Species') # (This will not happen,
58  sys.exit(1) # but always check errors.)

def libsbml.SBase.getAncestorOfType (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

getAncestorOfType(int type, string pkgName)   SBase
getAncestorOfType(int type)   SBase

Each variant is described separately below.


Method variant with the following signature:
getAncestorOfType(int type, string pkgName = 'core')

Returns the first ancestor object that has the given SBML type code from the given package.

LibSBML attaches an identifying code to every kind of SBML object. These are known as SBML type codes. In the Python language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbml. The names of the type codes all begin with the characters SBML_.

This method searches the tree of objects that are parents of this object, and returns the first one that has the given SBML type code from the given pkgName.

Parameters
typethe SBML type code of the object sought.
pkgName(optional) the short name of an SBML Level 3 package to which the sought-after object must belong.
Returns
the ancestor SBML object of this SBML object that corresponds to the given SBML object type code, or None if no ancestor exists.
Warning
The optional argument pkgName must be used for all type codes from SBML Level 3 packages. Otherwise, the function will search the 'core' namespace alone, not find any corresponding elements, and return None.
Note
Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value. This is not to be intepreted as a Python keyword argument; the use of a parameter name followed by an equals sign followed by a value is only meant to indicate a default value if the argument is not provided at all. It is not a keyword in the Python sense.

the ancestor SBML object of this SBML object that corresponds to the given SBML object type code, or None if no ancestor exists.
Warning
The optional argument pkgName must be used for all type codes from SBML Level 3 packages. Otherwise, the function will search the 'core' namespace alone, not find any corresponding elements, and return None.

def libsbml.SBase.getAnnotation (   self,
  args 
)
inherited

Returns the content of the 'annotation' subelement of this object as a tree of XMLNode objects.

getAnnotation()   XMLNode
Whereas the SBML 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

The annotations returned by this method will be in XML form. LibSBML provides an object model and related interfaces for certain specific kinds of annotations, namely model history information and RDF content. See the ModelHistory, CVTerm and RDFAnnotationParser classes for more information about the facilities available.

Returns
the annotation of this SBML object as a tree of XMLNode objects.

def libsbml.SBase.getColumn (   self)
inherited

Returns the column number where this object first appears in the XML representation of the SBML document.

getColumn()   long
Returns
the column number of this SBML object. If this object was created programmatically and not read from a file, this method will return the value 0.
Note
The column number for each construct in an SBML model is set upon reading the model. The accuracy of the column number depends on the correctness of the XML representation of the model, and on the particular XML parser library being used. The former limitation relates to the following problem: if the model is actually invalid XML, then the parser may not be able to interpret the data correctly and consequently may not be able to establish the real column number. The latter limitation is simply that different parsers seem to have their own accuracy limitations, and out of all the parsers supported by libSBML, none have been 100% accurate in all situations. (At this time, libSBML supports the use of libxml2, Expat and Xerces.)

)
inherited

Returns the nth disabled plug-in object (extension interface) for an SBML Level 3 package extension.

If no such plugin exists, None is returned.

SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism.

def libsbml.Group.getElementName (   self)

Returns the XML element name of this Group object.

getElementName()   string

For Group, the XML element name is always 'group'.

Returns
the name of this element, i.e. 'group'.
def libsbml.Group.getId (   self)

Returns the value of the 'id' attribute of this Group.

getId()   string
Returns
the value of the 'id' attribute of this Group as a string.
def libsbml.SBase.getIdAttribute (   self)
inherited

Returns the value of the 'id' attribute of this SBML object.

getIdAttribute()   string
The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z'
digit  ::= '0'..'9'
idChar ::= letter | digit | '_'
SId    ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return False for objects of these classes.

With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Returns
the id of this SBML object, if set and valid for this level and version of SBML; an empty string otherwise.
Note
Because of the inconsistent behavior of this function with respect to assignments and rules, callers should use getIdAttribute() instead.

def libsbml.Group.getKind (   self)

Returns the value of the 'kind' attribute of this Group.

getKind()   long
The attribute 'kind' on a Group object is used to indicate the nature of the group defined by a particular Group instance. In the SBML Level 3 Version 1 Group specification, there are only three allowable values for 'kind':
  • 'classification', to indicate that the group represents a class, and its members have an is-a relationship to the group.

  • 'partonomy', to indicate that the group represents a collection of parts, and its members have a part-of relationship to the group.

  • 'collection', to indicate that the grouping is merely a collection for convenience, without an implied relationship between the members.
Returns
the value of the 'kind' attribute of this Group as a long.

The possible values returned by this method are:

def libsbml.Group.getKindAsString (   self)

Returns the value of the 'kind' attribute of this Group.

getKindAsString()   string
The attribute 'kind' on a Group object is used to indicate the nature of the group defined by a particular Group instance. In the SBML Level 3 Version 1 Group specification, there are only three allowable values for 'kind':
  • 'classification', to indicate that the group represents a class, and its members have an is-a relationship to the group.

  • 'partonomy', to indicate that the group represents a collection of parts, and its members have a part-of relationship to the group.

  • 'collection', to indicate that the grouping is merely a collection for convenience, without an implied relationship between the members.
Returns
the value of the 'kind' attribute of this Group as a string. The possible values returned by this method are:
  • 'classification'
  • 'partonomy'
  • 'collection'
  • 'unknown'
def libsbml.SBase.getLevel (   self)
inherited

Returns the SBML Level of the SBMLDocument object containing this object.

getLevel()   long
LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)
Returns

the line number of this SBML object. If this object was created programmatically and not read from a file, this method will return the value 0.
Note
The line number for each construct in an SBML model is set upon reading the model. The accuracy of the line number depends on the correctness of the XML representation of the model, and on the particular XML parser library being used. The former limitation relates to the following problem: if the model is actually invalid XML, then the parser may not be able to interpret the data correctly and consequently may not be able to establish the real line number. The latter limitation is simply that different parsers seem to have their own accuracy limitations, and out of all the parsers supported by libSBML, none have been 100% accurate in all situations.

Parameters
sida string representing the 'idRef' attribute of the Member object to retrieve.
Returns

The pointer that is returned by this function is not owned by the caller, but may be queried and modified. Any changes made will be reflected in any resulting SBML document containing the pointer's parent.
def libsbml.SBase.getMetaId (   self)
inherited

Returns the value of the 'metaid' attribute of this SBML object.

getMetaId()   string
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.
Returns
the meta-identifier of this SBML object.

Returns
the ModelHistory object attached to this object, or None if none exist.
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
def libsbml.Group.getName (   self)

Returns the value of the 'name' attribute of this Group.

getName()   string
Returns
the value of the 'name' attribute of this Group as a string.
def libsbml.SBase.getNamespaces (   self)
inherited

Returns a list of the XML Namespaces declared on the SBML document owning this object.

getNamespaces()   XMLNamespaces

The optional SBML element named 'notes', present on every major SBML component type (and in SBML Level 3, the 'message' subelement of Constraint), is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements conform to the definition of XHTML 1.0. However, the content cannot be entirely free-form; it must satisfy certain requirements defined in the SBML specifications for specific SBML Levels. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); this method implements a verification process that lets callers check whether the content of a given XMLNode object conforms to the SBML requirements for 'notes' and 'message' structure. Developers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations of using 'notes' in SBML. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

The 'notes' element content returned by this method will be in XML form, but libSBML does not provide an object model specifically for the content of notes. Callers will need to traverse the XML tree structure using the facilities available on XMLNode and related objects. For an alternative method of accessing the notes, see getNotesString().

Returns
the content of the 'notes' subelement of this SBML object as a tree structure composed of XMLNode objects.

SBML Level 3 consists of a Core definition that can be extended via optional SBML Level 3 packages. A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.
If a plugin is disabled, the package information it contains is no longer considered to be part of the SBML document for the purposes of searching the document or writing out the document. However, the information is still retained, so if the plugin is enabled again, the same information will once again be available, and will be written out to the final model.

def libsbml.SBase.getPrefix (   self)
inherited

Returns the XML namespace prefix of this element.

getPrefix()   string

This reports the XML namespace prefix chosen for this class of object in the current SBML document. This may be an empty string if the component has no explicit prefix (for instance, if it is a core SBML object placed in the default SBML namespace of the document). If it is not empty, then it corresponds to the XML namespace prefix used set the object, whatever that may be in a given SBML document.

Returns

def libsbml.SBase.getResourceBiologicalQualifier (   self,
  resource 
)
inherited

Returns the MIRIAM biological qualifier associated with the given resource.

getResourceBiologicalQualifier(string resource)   long

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include 'is' and 'has part', but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using valueswhose names begin with BQB_ in the interface class libsbml.

This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a valuewhose name begins with BQB_ from the interface class libsbml.

Parameters
resourcestring representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'.
Returns
the qualifier associated with the resource, or BQB_UNKNOWN if the resource does not exist.
Note
The set of MIRIAM biological qualifiers grows over time, although relatively slowly. The values are up to date with MIRIAM at the time of a given libSBML release. The set of values in list of BQB_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.
def libsbml.SBase.getResourceModelQualifier (   self,
  resource 
)
inherited

Returns the MIRIAM model qualifier associated with the given resource.

getResourceModelQualifier(string resource)   long

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is 'isDerivedFrom', to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using valueswhose names begin with BQM_ in the interface class libsbml.

This method method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have model qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of type of model qualifier associated with that resource as a valuewhose name begins with BQM_ from the interface class libsbml.

Parameters
resourcestring representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'.
Returns
the model qualifier type associated with the resource, or BQM_UNKNOWN if the resource does not exist.
Note
The set of MIRIAM model qualifiers grows over time, although relatively slowly. The values are up to date with MIRIAM at the time of a given libSBML release. The set of values in list of BQM_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.
def libsbml.SBase.getSBMLDocument (   self,

inherited

Returns the SBMLDocument object containing this object instance.

getSBMLDocument()   SBMLDocument
LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)

def libsbml.SBase.getSBOTerm (   self)
inherited

Returns the integer portion of the value of the 'sboTerm' attribute of this object.

getSBOTerm()   int
Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.
Returns
the value of the 'sboTerm' attribute as an integer, or -1 if the value is not set.
def libsbml.SBase.getSBOTermAsURL (   self)
inherited

Returns the URL representation of the 'sboTerm' attribute of this object.

getSBOTermAsURL()   string

This method returns the entire SBO identifier as a text string in the form http://identifiers.org/biomodels.sbo/SBO:NNNNNNN'.

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.
Returns
the value of the 'sboTerm' attribute as an identifiers.org URL, or an empty string if the value is not set.
def libsbml.SBase.getSBOTermID (   self)
inherited

Returns the string representation of the 'sboTerm' attribute of this object.

SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.
Returns
the value of the 'sboTerm' attribute as a string (its value will be of the form 'SBO:NNNNNNN'), or an empty string if the value is not set.
def libsbml.Group.getTypeCode (   self)

Returns the libSBML type code for this Group object.

getTypeCode()   int
LibSBML attaches an identifying code to every kind of SBML object. These are integer constants known as SBML type codes. The names of all the codes begin with the characters SBML_. In the Python language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbml. Note that different Level 3 package plug-ins may use overlapping type codes; to identify the package to which a given object belongs, call the SBase.getPackageName() method on the object.

The exception to this is lists: all SBML-style list elements have the type SBML_LIST_OF, regardless of what package they are from.

Returns
the SBML type code for this object: SBML_GROUPS_GROUP.
Warning
The specific integer values of the possible type codes may be reused by different libSBML plug-ins for SBML Level 3. packages, To fully identify the correct code, it is necessary to invoke both getPackageName() and getTypeCode() (or ListOf.getItemTypeCode()).

def libsbml.SBase.getURI (   self)
inherited

Gets the namespace URI to which this element belongs to.

getURI()   string

For example, all elements that belong to SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/core'; all elements that belong to Layout Extension Version 1 for SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/layout/version1'.

This function first returns the URI for this element by looking into the SBMLNamespaces object of the document with the its package name. If not found, it will then look for the namespace associated with the element itself.

Returns
the URI of this element, as a text string.

def libsbml.SBase.isSetAnnotation (   self)
inherited

Predicate returning True if this object's 'annotation' subelement exists and has content.

isSetAnnotation()   bool

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

def libsbml.SBase.isSetIdAttribute (   self)
inherited

Predicate returning True if this object's 'id' attribute is set.

isSetIdAttribute()   bool
The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z'
digit  ::= '0'..'9'
idChar ::= letter | digit | '_'
SId    ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return False for objects of these classes.

With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Returns
True if the 'id' attribute of this SBML object is set, False otherwise.

def libsbml.Group.isSetKind (   self)

Predicate returning True if this Group's 'kind' attribute is set.

isSetKind()   bool
Returns
True if this Group's 'kind' attribute has been set, otherwise False is returned.
The attribute 'kind' on a Group object is used to indicate the nature of the group defined by a particular Group instance. In the SBML Level 3 Version 1 Group specification, there are only three allowable values for 'kind':
  • 'classification', to indicate that the group represents a class, and its members have an is-a relationship to the group.

  • 'partonomy', to indicate that the group represents a collection of parts, and its members have a part-of relationship to the group.

  • 'collection', to indicate that the grouping is merely a collection for convenience, without an implied relationship between the members.
def libsbml.SBase.isSetMetaId (   self)
inherited

Predicate returning True if this object's 'metaid' attribute is set.

isSetMetaId()   bool
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.
Returns
True if the 'metaid' attribute of this SBML object is set, False otherwise.

isSetModelHistory()   bool
Returns
True if the ModelHistory of this object is set, False otherwise.
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
def libsbml.Group.isSetName (   self)

Predicate returning True if this Group's 'name' attribute is set.

isSetName()   bool
Returns
True if this Group's 'name' attribute has been set, otherwise False is returned.
def libsbml.SBase.isSetNotes (   self)
inherited

Predicate returning True if this object's 'notes' subelement exists and has content.

isSetNotes()   bool

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

Returns
True if a 'notes' subelement exists, False otherwise.

def libsbml.SBase.isSetSBOTerm (   self)
inherited

Predicate returning True if this object's 'sboTerm' attribute is set.

isSetSBOTerm()   bool
Returns
True if the 'sboTerm' attribute of this SBML object is set, False otherwise.
def libsbml.SBase.isSetUserData (   self)
inherited

Predicate returning true or false depending on whether the user data of this element has been set.

isSetUserData()   bool
The user data associated with an SBML object can be used by an application developer to attach custom information to that object in the model. In case of a deep copy, this data will passed as-is. The data attribute will never be interpreted by libSBML.
Returns
boolean, True if this object's user data has been set, False otherwise.
def libsbml.SBase.matchesRequiredSBMLNamespacesForAddition (   self,
  args 
)
inherited

Returns True if this object's set of XML namespaces are a subset of the given object's XML namespaces.

matchesRequiredSBMLNamespacesForAddition(SBase sb)   bool
The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core. A common approach to using libSBML's SBMLNamespaces facilities is to create an SBMLNamespaces object somewhere in a program once, then hand that object as needed to object constructors that accept SBMLNamespaces as arguments.
Parameters
sban object to compare with respect to namespaces.
Returns
boolean, True if this object's collection of namespaces is a subset of sb's, False otherwise.
def libsbml.SBase.matchesSBMLNamespaces (   self,
  args 
)
inherited

Returns True if this object's set of XML namespaces are the same as the given object's XML namespaces.

matchesSBMLNamespaces(SBase sb)   bool

Returns
boolean, True if this object's collection of namespaces is the same as sb's, False otherwise.
def libsbml.SBase.removeFromParentAndDelete (   self)
inherited

Removes this object from its parent.

removeFromParentAndDelete()   int

If the parent was storing this object as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). This is a pure virtual method, as every SBase element has different parents, and therefore different methods of removing itself. Will fail (and not delete itself) if it has no parent object. This function is designed to be overridden, but for all objects whose parent is of the class ListOf, the default implementation will work.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.Group.removeMember (   self,
  args 
)

This method has multiple variants; they differ in the arguments they accept.

removeMember(long  n)   Member
removeMember(string sid)   Member

Each variant is described separately below.


Method variant with the following signature:
removeMember(long n)

Removes the nth Member from this Group and returns a pointer to it.

Parameters
na long integer representing the index of the Member to remove.
Returns
a pointer to the nth Member in this Group.
Warning
The pointer that is returned by this function is owned by the caller, who is responsible for deleting it. Any changes made to the element will not be reflected in any resulting SBML document unless the element is added to an SBML Document. Even in this case, the element's deletion is still the responsibility of the caller with two exceptions: if it is used as the 'disownedItem' in theListOf.appendAndOwn() or ListOf.insertAndOwn() functions. All other functions in libsbml add a copy of the element, and do not transfer ownership of the pointer.

Parameters
sida string representing the identifier of the Member to remove.
Returns
the Member in this Group based on the identifier or None if no such Member exists.
Warning
The pointer that is returned by this function is owned by the caller, who is responsible for deleting it.

def libsbml.SBase.removeTopLevelAnnotationElement (   self,
  args 
)
inherited

Removes the top-level element within the 'annotation' subelement of this SBML object with the given name and optional URI.

removeTopLevelAnnotationElement(string elementName, string elementURI, bool removeEmpty)   int
removeTopLevelAnnotationElement(string elementName, string elementURI)   int
removeTopLevelAnnotationElement(string elementName)   int

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Calling this method allows a particular annotation element to be removed whilst the remaining annotations remain intact.

Parameters
elementNamea string representing the name of the top level annotation element that is to be removed.
elementURIan optional string that is used to check both the name and URI of the top level element to be removed.
removeEmptyif after removing of the element, the annotation is empty, and the removeEmpty argument is true, the annotation node will be deleted (default).
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

Note
Owing to the way that language interfaces are created in libSBML, this documentation may show methods that define default values for parameters with text that has the form parameter = value. This is not to be intepreted as a Python keyword argument; the use of a parameter name followed by an equals sign followed by a value is only meant to indicate a default value if the argument is not provided at all. It is not a keyword in the Python sense.
def libsbml.SBase.renameMetaIdRefs (   self,
  oldid,
  newid 
)
inherited

Replaces all uses of a given meta identifier attribute value with another value.

renameMetaIdRefs(string oldid, string newid)
In SBML, object 'meta' identifiers are of the XML data type ID; the SBML object attribute itself is typically named metaid. All attributes that hold values referring to values of type ID are of the XML data type IDREF. They are also sometimes informally referred to as 'metaid refs', in analogy to the SBML-defined type SIdRef.

This method works by looking at all meta-identifier attribute values, comparing the identifiers to the value of oldid. If any matches are found, the matching identifiers are replaced with newid. The method does not descend into child elements.

Parameters
oldidthe old identifier.
newidthe new identifier.
def libsbml.SBase.renameSIdRefs (   self,
  oldid,
  newid 
)
inherited

Replaces all uses of a given SIdRef type attribute value with another value.

renameSIdRefs(string oldid, string newid)
In SBML, object identifiers are of a data type called SId. In SBML Level 3, an explicit data type called SIdRef was introduced for attribute values that refer to SId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as 'referring to an identifier', but the effective data type was the same as SIdRef in Level 3. These and other methods of libSBML refer to the type SIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.

This method works by looking at all attributes and (if appropriate) mathematical formulas in MathML content, comparing the referenced identifiers to the value of oldid. If any matches are found, the matching values are replaced with newid. The method does not descend into child elements.

Parameters
oldidthe old identifier.
newidthe new identifier.
def libsbml.SBase.renameUnitSIdRefs (   self,
  oldid,
  newid 
)
inherited

Replaces all uses of a given UnitSIdRef type attribute value with another value.

renameUnitSIdRefs(string oldid, string newid)
In SBML, unit definitions have identifiers of type UnitSId. In SBML Level 3, an explicit data type called UnitSIdRef was introduced for attribute values that refer to UnitSId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as 'referring to a unit identifier', but the effective data type was the same as UnitSIdRef in Level 3. These and other methods of libSBML refer to the type UnitSIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.

This method works by looking at all unit identifier attribute values (including, if appropriate, inside mathematical formulas), comparing the referenced unit identifiers to the value of oldid. If any matches are found, the matching values are replaced with newid. The method does not descend into child elements.

Parameters
oldidthe old identifier.
newidthe new identifier.
def libsbml.SBase.replaceTopLevelAnnotationElement (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

replaceTopLevelAnnotationElement(XMLNode annotation)   int
replaceTopLevelAnnotationElement(string annotation)   int

Each variant is described separately below.


Method variant with the following signature:
replaceTopLevelAnnotationElement(XMLNode annotation)

Replaces the given top-level element within the 'annotation' subelement of this SBML object and with the annotation element supplied.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

This method determines the name of the element to be replaced from the annotation argument. Functionally it is equivalent to calling removeTopLevelAnnotationElement(name) followed by calling appendAnnotation(annotation_with_name), with the exception that the placement of the annotation element remains the same.

Parameters
annotationXMLNode representing the replacement top level annotation.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.SBase.setAnnotation (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

setAnnotation(XMLNode annotation)   int
setAnnotation(string annotation)   int

Each variant is described separately below.


Method variant with the following signature:
setAnnotation(XMLNode annotation)

Sets the value of the 'annotation' subelement of this SBML object.

The content of annotation is copied, and any previous content of this object's 'annotation' subelement is deleted.

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Call this method will result in any existing content of the 'annotation' subelement to be discarded. Unless you have taken steps to first copy and reconstitute any existing annotations into the annotation that is about to be assigned, it is likely that performing such wholesale replacement is unfriendly towards other software applications whose annotations are discarded. An alternative may be to use SBase.appendAnnotation() or SBase.appendAnnotation().

Parameters
annotationan XML structure that is to be used as the new content of the 'annotation' subelement of this object.
Returns
integer value indicating success/failure of the function. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

def libsbml.Group.setId (   self,
  id 
)

Sets the value of the 'id' attribute of this Group.

setId(string id)   int
Parameters
idstring value of the 'id' attribute to be set.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are: Calling this function with id = None or an empty string is equivalent to calling unsetId().
def libsbml.SBase.setIdAttribute (   self,
  sid 
)
inherited

Sets the value of the 'id' attribute of this SBML object.

setIdAttribute(string sid)   int
The string sid is copied.
The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z'
digit  ::= '0'..'9'
idChar ::= letter | digit | '_'
SId    ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.

Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return False for objects of these classes.

With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Parameters
sidthe string to use as the identifier of this object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.Group.setKind (   self,
  args 
)

This method has multiple variants; they differ in the arguments they accept.

setKind(long  kind)   int
setKind(string kind)   int

Each variant is described separately below.


Method variant with the following signature:
setKind(long kind)

Sets the value of the 'kind' attribute of this Group.

Parameters
kindint value of the 'kind' attribute to be set. The value must be one of the predefined constants that represent valid SBML Level 3 Version 1 Group 'kind' names, which means it must be one of the following values:
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
The attribute 'kind' on a Group object is used to indicate the nature of the group defined by a particular Group instance. In the SBML Level 3 Version 1 Group specification, there are only three allowable values for 'kind':
  • 'classification', to indicate that the group represents a class, and its members have an is-a relationship to the group.

  • 'partonomy', to indicate that the group represents a collection of parts, and its members have a part-of relationship to the group.

  • 'collection', to indicate that the grouping is merely a collection for convenience, without an implied relationship between the members.

Method variant with the following signature:
setKind(string kind)

Sets the value of the 'kind' attribute of this Group.

Parameters
kindstring of the 'kind' attribute to be set. The value must be one of the following possible strings:
  • 'classification'
  • 'partonomy'
  • 'collection'
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
The attribute 'kind' on a Group object is used to indicate the nature of the group defined by a particular Group instance. In the SBML Level 3 Version 1 Group specification, there are only three allowable values for 'kind':

  • 'partonomy', to indicate that the group represents a collection of parts, and its members have a part-of relationship to the group.

  • 'collection', to indicate that the grouping is merely a collection for convenience, without an implied relationship between the members.
def libsbml.SBase.setMetaId (   self,
  metaid 
)
inherited

Sets the value of the meta-identifier attribute of this SBML object.

setMetaId(string metaid)   int
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

The string metaid is copied.

Parameters
metaidthe identifier string to use as the value of the 'metaid' attribute.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.SBase.setModelHistory (   self,
  history 
)
inherited

Sets the ModelHistory of this object.

setModelHistory(ModelHistory history)   int

The content of history is copied, and this object's existing model history content is deleted.

Parameters
historyModelHistory of this object.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
def libsbml.Group.setName (   self,
  name 
)

Sets the value of the 'name' attribute of this Group.

setName(string name)   int
Parameters
namestring value of the 'name' attribute to be set.
Returns
integer value indicating success/failure of the function. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value: Calling this function with name = None or an empty string is equivalent to calling unsetName().
def libsbml.SBase.setNamespaces (   self,
  xmlns 
)
inherited

Sets the namespaces relevant of this SBML object.

setNamespaces(XMLNamespaces xmlns)   int

The content of xmlns is copied, and this object's existing namespace content is deleted.

The SBMLNamespaces object encapsulates SBML Level/Version/namespaces information. It is used to communicate the SBML Level, Version, and (in Level 3) packages used in addition to SBML Level 3 Core.

Parameters
xmlnsthe namespaces to set.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.setNotes (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

setNotes(XMLNode notes)   int
setNotes(string notes, bool addXHTMLMarkup)   int
setNotes(string notes)   int

Each variant is described separately below.


Method variant with the following signature:
setNotes(string notes, bool addXHTMLMarkup = false)

Sets the value of the 'notes' subelement of this SBML object to a copy of the string notes.

The content of notes is copied, and any existing content of this object's 'notes' subelement is deleted.

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

The following code illustrates a very simple way of setting the notes using this method. Here, the object being annotated is the whole SBML document, but that is for illustration purposes only; you could of course use this same approach to annotate any other SBML component.

1 try:
2  sbmlDoc = SBMLDocument(3, 1)
3 except ValueError:
4  print('Could not create SBMLDocument object')
5  sys.exit(1)
6 
7 note = '<body xmlns='http://www.w3.org/1999/xhtml'><p>here is my note</p></body>'
8 
9 status = sbmlDoc.setNotes(note)
10 if status != LIBSBML_OPERATION_SUCCESS:
11  # Do something to handle the error here.
12  print('Unable to set notes on the SBML document object')
13  sys.exit(1)
Parameters
notesan XML string that is to be used as the content of the 'notes' subelement of this object.
addXHTMLMarkupa boolean indicating whether to wrap the contents of the notes argument with XHTML paragraph (<p>) tags. This is appropriate when the string in notes does not already containg the appropriate XHTML markup.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.SBase.setSBOTerm (   self,
  args 
)
inherited

This method has multiple variants; they differ in the arguments they accept.

setSBOTerm(int value)   int
setSBOTerm(string sboid)   int

Each variant is described separately below.


Method variant with the following signature:
setSBOTerm(int value)

Sets the value of the 'sboTerm' attribute.

Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.
Parameters

setSBOTerm()

Method variant with the following signature:
setSBOTerm(string sboid)

Sets the value of the 'sboTerm' attribute by string.

Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.
Parameters
sboidthe SBO identifier string of the form 'SBO:NNNNNNN'.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

setSBOTerm()
def libsbml.SBase.toSBML (   self)
inherited

Returns a string consisting of a partial SBML corresponding to just this object.

toSBML()   string
Returns
the partial SBML that describes this SBML object.
Warning
This is primarily provided for testing and debugging purposes. It may be removed in a future version of libSBML.
def libsbml.SBase.toXMLNode (   self)
inherited

Returns this element as an XMLNode.

toXMLNode()   XMLNode
Returns
this element as an XMLNode.
Warning
This operation is computationally expensive, because the element has to be fully serialized to a string and then parsed into the XMLNode structure. Attempting to convert a large tree structure (e.g., a large Model) may consume significant computer memory and time.
def libsbml.SBase.unsetAnnotation (   self)
inherited

Unsets the value of the 'annotation' subelement of this SBML object.

unsetAnnotation()   int

Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.

SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Returns
integer value indicating success/failure of the function. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

def libsbml.SBase.unsetCVTerms (   self)
inherited

Clears the list of CVTerm objects attached to this SBML object.

unsetCVTerms()   int
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.Group.unsetId (   self)

Unsets the value of the 'id' attribute of this Group.

unsetId()   int
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.unsetIdAttribute (   self)
inherited

Unsets the value of the 'id' attribute of this SBML object.

unsetIdAttribute()   int

Most (but not all) objects in SBML include two common attributes: 'id' and 'name'. The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier.

Returns
integer value indicating success/failure of the function. The possible values returned by this function are:

def libsbml.Group.unsetKind (   self)

Unsets the value of the 'kind' attribute of this Group.

unsetKind()   int
Returns
integer value indicating success/failure of the function. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:
The attribute 'kind' on a Group object is used to indicate the nature of the group defined by a particular Group instance. In the SBML Level 3 Version 1 Group specification, there are only three allowable values for 'kind':
  • 'classification', to indicate that the group represents a class, and its members have an is-a relationship to the group.

  • 'partonomy', to indicate that the group represents a collection of parts, and its members have a part-of relationship to the group.

  • 'collection', to indicate that the grouping is merely a collection for convenience, without an implied relationship between the members.
def libsbml.SBase.unsetMetaId (   self)
inherited

Unsets the value of the 'metaid' attribute of this SBML object.

unsetMetaId()   int
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.unsetModelHistory (   self)
inherited

Unsets the ModelHistory object attached to this object.

unsetModelHistory()   int
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
Note
In SBML Level 2, model history annotations were only permitted on the Model element. In SBML Level 3, they are permitted on all SBML components derived from SBase.
def libsbml.Group.unsetName (   self)

Unsets the value of the 'name' attribute of this Group.

unsetName()   int
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
def libsbml.SBase.unsetNotes (   self)
inherited

Unsets the value of the 'notes' subelement of this SBML object.

unsetNotes()   int

The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.

The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

Returns
integer value indicating success/failure of the function. This particular function only does one thing irrespective of user input or object state, and thus will only return a single value:

def libsbml.SBase.unsetUserData (   self)
inherited

Unsets the user data of this element.

unsetUserData()   int
The user data associated with an SBML object can be used by an application developer to attach custom information to that object in the model. In case of a deep copy, this data will passed as-is. The data attribute will never be interpreted by libSBML.
Returns
integer value indicating success/failure of the function. The possible values returned by this function are:
