Class NamedGraphStatementIterator

java.lang.Object
  com.hp.hpl.jena.util.iterator.NiceIterator
      com.hp.hpl.jena.util.iterator.WrappedIterator
          com.hp.hpl.jena.rdf.model.impl.StmtIteratorImpl
              de.fuberlin.wiwiss.ng4j.impl.NamedGraphStatementIterator

All Implemented Interfaces:

StmtIterator, ClosableIterator, ExtendedIterator, Iterator

public class NamedGraphStatementIterator
extends com.hp.hpl.jena.rdf.model.impl.StmtIteratorImpl

Helper implementation of StmtIterator that wraps a StmtIterator and returns all of its elements as NamedGraphStatements instead of simple Jena Statements. This is somewhat hackish, but I couldn't figure out another way to make sure that NamedGraphModel always returns NamedGraphStatements.
