Description copied from interface: BNodeFactory

Creates a new bNode.

Specified by:

createBNode in interface BNodeFactory

Returns:

An object representing the bNode.

createBNode

public BNode createBNode(String nodeID)

Description copied from interface: BNodeFactory

                                 Value object)

Description copied from interface: ValueFactory

Creates a new statement with the supplied subject, predicate and object.

Specified by:

createStatement in interface ValueFactory

Parameters:

subject - The statement's subject.

predicate - The statement's predicate.

object - The statement's object.

Returns:

The created statement.

createStatement

public Statement createStatement(Resource subject,
                                 URI predicate,
                                 Value object,
                                 Resource context)

Description copied from interface: ValueFactory

Creates a new statement with the supplied subject, predicate and object and associated context.

Specified by:

createStatement in interface ValueFactory

Parameters:

createURI

public URI createURI(String uri)

Description copied from interface: URIFactory

Creates a new URI from the supplied string-representation.

Specified by:

createURI in interface URIFactory

Parameters:

uri - A string-representation of a URI.

Returns:

An object representing the URI.

createURI

public URI createURI(String namespace,
                     String localName)

Description copied from interface: URIFactory

Creates a new URI from the supplied namespace and local name. Calling this method is funtionally equivalent to calling createURI(namespace+localName), but allows the ValueFactory to reuse supplied namespace and local name strings whenever possible. Note that the values returned by URI.getNamespace() and URI.getLocalName() are not necessarily the same as the values that are supplied to this method.

Specified by:

createURI in interface URIFactory

Parameters:

namespace - The URI's namespace.

localName - The URI's local name.
