Detailed Description

groups Base extension class for the package.

This class of objects is defined by libSBML only and has no direct equivalent in terms of SBML components. This class is not prescribed by the SBML specifications, although it is used to implement features defined in SBML.

This is the Groups package extension of the SBMLExtension class that is used to facilitate libSBML plug-ins in the implementation of an SBMLLevel 3 package.

Member Function Documentation

void SBMLExtension::addL2Namespaces ( XMLNamespaces xmlns) const
virtualinherited

Adds the package's Level 2 namespace(s).

This method is related to special facilities designed to support legacy behaviors surrounding SBML Level 2 models. Due to the historical background of the SBML Layout package, libSBML implements special behavior for that package: it always creates a Layout plugin object for any SBML Level 2 document it reads in, regardless of whether that document actually uses Layout constructs. Since Level 2 does not use namespaces on the top level of the SBML document object, libSBML simply keys off the fact that the model is a Level 2 model. To allow the extensions for the Layout and Render (and possibly other) packages to support this behavior, the SBMLExtension class contains special methods to allow packages to hook themselves into the Level 2 parsing apparatus when necessary.

This virtual method should be overridden by all package extensions that want to serialize to an SBML Level 2 annotation. In Level 2, the XML namespace declaration for the package is not placed on the top-level SBML document object but rather inside individual annotations. addL2Namespaces() is invoked automatically for Level 2 documents when an SBMLExtensionNamespace object is created; removeL2Namespaces() is automatically invoked by SBMLDocument to prevent the namespace(s) from being put on the top-level SBML Level 2 element (because Level 2 doesn't support namespaces there); and enableL2NamespaceForDocument() is called automatically when any SBML document (of any Level/Version) is read in.

Parameters
xmlnsan XMLNamespaces object that will be used for the annotation. Implementation should override this method with something that adds the package's namespace(s) to the set of namespaces in xmlns. For instance, here is the code from the Layout package extension:
if (!xmlns->containsUri( LayoutExtension::getXmlnsL2()))
xmlns->add(LayoutExtension::getXmlnsL2(), "layout");

Reimplemented in LayoutExtension, and RenderExtension.

GroupsExtension * GroupsExtension::clone ( ) const
virtual

Creates and returns a deep copy of this GroupsExtension object.

Returns
a (deep) copy of this GroupsExtension object.

Implements SBMLExtension.

void SBMLExtension::enableL2NamespaceForDocument ( SBMLDocument doc) const
virtualinherited

Called to enable the package on the SBMLDocument object.

This method is related to special facilities designed to support legacy behaviors surrounding SBML Level 2 models. Due to the historical background of the SBML Layout package, libSBML implements special behavior for that package: it always creates a Layout plugin object for any SBML Level 2 document it reads in, regardless of whether that document actually uses Layout constructs. Since Level 2 does not use namespaces on the top level of the SBML document object, libSBML simply keys off the fact that the model is a Level 2 model. To allow the extensions for the Layout and Render (and possibly other) packages to support this behavior, the SBMLExtension class contains special methods to allow packages to hook themselves into the Level 2 parsing apparatus when necessary.

This virtual method should be overridden by all package extensions that want to serialize to an SBML Level 2 annotation. In Level 2, the XML namespace declaration for the package is not placed on the top-level SBML document object but rather inside individual annotations. addL2Namespaces() is invoked automatically for Level 2 documents when an SBMLExtensionNamespace object is created; removeL2Namespaces() is automatically invoked by SBMLDocument to prevent the namespace(s) from being put on the top-level SBML Level 2 element (because Level 2 doesn't support namespaces there); and enableL2NamespaceForDocument() is called automatically when any SBML document (of any Level/Version) is read in.

Parameters
docthe SBMLDocument object for the model. Implementations should override this method with something that enables the package based on the package's namespace(s). For example, here is the code from the Layout package extension:
if (doc->getLevel() == 2)
doc->enablePackage(LayoutExtension::getXmlnsL2(), "layout", true);

Reimplemented in LayoutExtension, and RenderExtension.

virtual

Returns a GroupsPkgNamespaces object.

Parameters
urithe string of the URI that represents one of the versions of the "groups" package.
Returns
GroupsPkgNamespaces object corresponding to the given URI of this package, or NULL if the given URI is not defined in the "groups" package.

Implements SBMLExtension.

const char * GroupsExtension::getStringFromTypeCode ( int  typeCode) const
virtual

Takes a type code of the “groups” package and returns a string describing the code.

Parameters
typeCodea libSBML type code defined by the libSBML extension implementing support for the SBML Level 3 “groups” package.
Returns
a text string representing the type code given by typeCode. If the type code is unrecognized for this implementation of the libSBML “groups” package, the string returned will be "(Unknown SBML Groups Type)".

inherited

Returns the nth XML namespace URI.

Parameters
nthe index number of the namespace URI being sought.
Returns
a string representing the XML namespace URI understood to be supported by this package. An empty string will be returned if there is no nth URI.

Returns a string representing the SBML XML namespace of this SBML Level 3 package.

Parameters
sbmlLevelthe level of SBML.
sbmlVersionthe version of SBML.
pkgVersionthe version of this package.
Returns
a string representing the name of this package ("groups").

The namespace URI constructed by this method corresponds to the combination of the Level and Version of SBML, and the Version of the SBML Level 3 package. (At the time of this writing, the only SBML Level that supports packages is Level 3, so the value of sbmlLevel is necessarily always 3.)

Implements SBMLExtension.

virtual

Returns the Version within the SBML Level for the given URI of this package.

Parameters
urithe string of the URI that represents one of the versions of the "groups" package.

bool SBMLExtension::isInUse ( SBMLDocument doc) const
virtualinherited

Returns
a boolean indicating whether the extension is actually being used by the document.

Reimplemented in LayoutExtension, and RenderExtension.

Parameters
rhsthe GroupsExtension object whose values are to be used as the basis of the assignment.
void SBMLExtension::removeL2Namespaces ( XMLNamespaces xmlns) const
virtualinherited

Removes the package's Level 2 namespace(s).

This method is related to special facilities designed to support legacy behaviors surrounding SBML Level 2 models. Due to the historical background of the SBML Layout package, libSBML implements special behavior for that package: it always creates a Layout plugin object for any SBML Level 2 document it reads in, regardless of whether that document actually uses Layout constructs.

Parameters
xmlnsan XMLNamespaces object that will be used for the annotation. Implementations should override this method with something that removes the package's namespace(s) from the set of namespaces in xmlns. For instance, here is the code from the Layout package extension:
for (int n = 0; n < xmlns->getNumNamespaces(); n++)
{
if (xmlns->getURI(n) == LayoutExtension::getXmlnsL2())
xmlns->remove(n);
}
