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

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