Method Detail

getId

public AnonId getId()

Description copied from interface: Resource

Returns an a unique identifier for anonymous resources.

Following copied from interface: com.hp.hpl.mesa.rdf.jena.model.Resource

Returns:

A unique id for an anonymous resource.

Throws:

RDFException - Generic RDF exception.
