Class RDFIterators.RDFListIterator

java.lang.Object
  it.uniroma2.art.owlart.navigation.RDFIteratorImpl<ARTNode>
      it.uniroma2.art.owlart.utilities.RDFIterators.RDFListIterator

All Implemented Interfaces:

ARTNodeIterator, RDFIterator<ARTNode>, java.util.Iterator<ARTNode>

Enclosing class:

RDFIterators

public static class RDFIterators.RDFListIterator
extends RDFIteratorImpl<ARTNode>
implements ARTNodeIterator

This iterator class provides facilities for managing resources of type rdf:List It is already used in OWL and SKOS methods such as OWLModelImpl.parseDataRange(ARTResource, ARTResource...)

Constructor Summary

RDFIterators.RDFListIterator(OWLModel model, ARTResource list, boolean inference, ARTResource... graphs)

Method Summary

void	close() closes the iterator and release resources
ARTNode	getNext() gets the next element of the iterator, and advances over the data stream (roughly equivalent to traditional next() iterator method)
boolean	streamOpen() tells if the data stream associated to this iterator is not empty (roughly equivalent to traditional hasNext() iterator method)
