Method Summary

Modifier and Type	Method and Description
boolean	add(Resource subj, IRI pred, Value obj, Resource... contexts) Deprecated. Adds one or more statements to the graph.
ValueFactory	getValueFactory() Deprecated. SimpleValueFactory.getInstance() will obtain a default value factory implementation. If you are working with the Repository API, then Repository instances also supply a getValueFactory() method.
Iterator<Statement>	match(Resource subj, IRI pred, Value obj, Resource... contexts) Deprecated. The preferred alternative is Model.filter(org.eclipse.rdf4j.model.Resource, org.eclipse.rdf4j.model.IRI, org.eclipse.rdf4j.model.Value, org.eclipse.rdf4j.model.Resource...).iterator().

Method Detail

getValueFactory

@Deprecated
ValueFactory getValueFactory()

Deprecated. SimpleValueFactory.getInstance() will obtain a default value factory implementation. If you are working with the Repository API, then Repository instances also supply a getValueFactory() method.

Gets the value factory for this graph.

add

boolean add(Resource subj,
            IRI pred,
            Value obj,
            Resource... contexts)

Deprecated.

Adds one or more statements to the graph. This method creates a statement for each specified context and adds those to the graph. If no contexts are specified, a single statement with no associated context is added.

Parameters:

subj - The statement's subject, must not be null.

pred - The statement's predicate, must not be null.

obj - The statement's object, must not be null.

contexts - The contexts to add statements to.

match

@Deprecated
Iterator<Statement> match(Resource subj,
                                      IRI pred,
                                      Value obj,
                                      Resource... contexts)

Deprecated. The preferred alternative is Model.filter(org.eclipse.rdf4j.model.Resource, org.eclipse.rdf4j.model.IRI, org.eclipse.rdf4j.model.Value, org.eclipse.rdf4j.model.Resource...).iterator().

Gets the statements with the specified subject, predicate, object and (optionally) context. The subject, predicate and object parameters can be null to indicate wildcards. The contexts parameter is a wildcard and accepts zero or more values. If no contexts are specified, statements will match disregarding their context. If one or more contexts are specified, statements with a context matching one of these will match. Note: to match statements without an associated context, specify the value null and explicitly cast it to type Resource.

Examples: graph.match(s1, null, null) matches all statements that have subject s1,
graph.match(null, null, null, c1) matches all statements that have context c1,
graph.match(null, null, null, (Resource)null) matches all statements that have no associated context,
graph.match(null, null, null, c1, c2, c3) matches all statements that have context c1 , c2 or c3.

Parameters:

subj - The subject of the statements to match, null to match statements with any subject.

pred - The predicate of the statements to match, null to match statements with any predicate.

obj - The object of the statements to match, null to match statements with any object.

contexts - The contexts of the statements to match. If no contexts are specified, statements will match disregarding their context. If one or more contexts are specified, statements with a context matching one of these will match.

Returns:

The statements that match the specified pattern.

Throws:

IllegalArgumentException - If a null-array is specified as the value for contexts. See OpenRDFUtil.verifyContextNotNull(Resource[]) for more info.
