Examples of com.hp.hpl.jena.rdf.model.ResIterator

com.hp.hpl.jena.rdf.model.ResIterator
An iterator which returns RDF Resources.
RDF iterators are standard Java iterators, except that they have an extra method that returns a specifically typed object, in this case RDF Resource, and have a close() method that should be called to free resources if the caller does not complete the iteration.
