Method Detail

getSubjectIterator

@Deprecated
public static Iterator<Resource> getSubjectIterator(Graph graph,
                                                                IRI pred,
                                                                Value obj,

Deprecated. since 2.0. Use Model.filter(Resource, IRI, Value, Resource...) and Model.subjects() instead.

Gets the subject of the statements with the specified predicate, object and (optionally) contexts from the supplied graph. Calling this method is equivalent to calling graph.match(null, pred, obj, contexts) and extracting the subjects of the matching statements from the returned iterator. See Graph.match(Resource, IRI, Value, Resource[]) for a description of the parameter values.

getSubjects

@Deprecated
public static Set<Resource> getSubjects(Graph graph,
                                                    IRI pred,
                                                    Value obj,
                                                    Resource... contexts)

Deprecated. since 2.0. Use Model.filter(Resource, IRI, Value, Resource...) and Model.subjects() instead.

Gets the subject of the statements with the specified predicate, object and (optionally) contexts from the supplied graph. Calling this method is equivalent to calling graph.match(null, pred, obj, contexts) and adding the subjects of the matching statements to a set. See Graph.match(Resource, IRI, Value, Resource[]) for a description of the parameter values.

getUniqueSubject

@Deprecated
public static Resource getUniqueSubject(Graph graph,
                                                    IRI pred,

                                             throws GraphUtilException

Deprecated. since 2.0. Use Model.filter(Resource, IRI, Value, Resource...) and Model.subjectResource() instead.

Gets the subject of the statement(s) with the specified predicate and object from the specified contexts in the supplied graph. The combination of predicate, object and contexts must match at least one statement. In case more than one statement matches -- for example statements from multiple contexts -- all these statements should have the same subject. A GraphUtilException is thrown if these conditions are not met. See Graph.match(Resource, IRI, Value, Resource[]) for a description of the parameter values.

Returns:

The subject of the matched statement(s).

Throws:

GraphUtilException - If the statements matched by the specified parameters do not have exactly one unique subject.
