Detailed Description

represents an RDF named graph that is stored in an RDF Repository.

Note that this interface inherits from XResource: the name of the graph is the string value of the RDF node. This is so that you can easily make RDF statements about named graphs.

Note that instances may be destroyed via XRepository::destroyGraph(). If a graph is destroyed, subsequent calls to addStatement(), removeStatements() will fail with an com::sun::star::container::NoSuchElementException.

Since: OOo 3.2

Member Function Documentation

◆ addStatement()

void addStatement	(	[in] XResource	Subject,
		[in] XURI	Predicate,
		[in] XNode	Object
	)
raises	(	com::sun::star::lang::IllegalArgumentException,
		com::sun::star::container::NoSuchElementException,
		RepositoryException
	)

adds a RDF statement to the graph.

Note that the ODF elements that can have metadata attached all implement the interface XMetadatable, which inherits from XResource, meaning that you can simply pass them in as arguments here, and it will magically work.

Parameters

Subject	the subject of the RDF triple.
Predicate	the predicate of the RDF triple.
Object	the object of the RDF triple.

Exceptions

com::sun::star::lang::IllegalArgumentException	if any parameter is `NULL`
com::sun::star::container::NoSuchElementException	if this graph does not exist in the repository any more
RepositoryException	if an error occurs when accessing the repository.

◆ clear()

void clear	(		)
raises	(	com::sun::star::container::NoSuchElementException,
		RepositoryException
	)

removes all statements from the graph.

Exceptions

com::sun::star::container::NoSuchElementException	if this graph does not exist in the repository any more
RepositoryException	if an error occurs when accessing the repository.

◆ getName()

XURI getName ( )

returns the name of the graph.

The name is unique within the repository.

Returns: the name of the graph

◆ getStatements()

com::sun::star::container::XEnumeration getStatements	(	[in] XResource	Subject,
		[in] XURI	Predicate,
		[in] XNode	Object
	)
raises	(	com::sun::star::container::NoSuchElementException,
		RepositoryException
	)

gets matching RDF statements from a graph.

Note that the ODF elements that can have metadata attached all implement the interface XMetadatable, which inherits from XResource, meaning that you can simply pass them in as arguments here, and it will magically work.

Any parameter may be NULL, which acts as a wildcard. For example, to get all statements about myURI: getStatements(myURI, null, null)

Parameters

Subject	the subject of the RDF triple.
Predicate	the predicate of the RDF triple.
Object	the object of the RDF triple.

Returns: an iterator over all RDF statements in the graph that match the parameters, represented as an enumeration of Statement

Exceptions

com::sun::star::container::NoSuchElementException	if this graph does not exist in the repository any more
RepositoryException	if an error occurs when accessing the repository.

See also: Statement

◆ removeStatements()

void removeStatements	(	[in] XResource	Subject,
		[in] XURI	Predicate,
		[in] XNode	Object
	)
raises	(	com::sun::star::container::NoSuchElementException,
		RepositoryException
	)

removes matching RDF statements from the graph.

Note that the ODF elements that can have metadata attached all implement the interface XMetadatable, which inherits from XResource, meaning that you can simply pass them in as arguments here, and it will magically work.

Any parameter may be NULL, which acts as a wildcard. For example, to remove all statements about myURI: removeStatement(myURI, null, null)

Parameters

Subject	the subject of the RDF triple.
Predicate	the predicate of the RDF triple.
Object	the object of the RDF triple.

Exceptions

com::sun::star::container::NoSuchElementException	if this graph does not exist in the repository any more
RepositoryException	if an error occurs when accessing the repository.
