public boolean hasNext()
throws RDFException
hasNext in interface ResIteratorRDFException - Generic RDF exception.
public Resource next()
throws java.util.NoSuchElementException,
RDFException
next in interface ResIteratorjava.util.NoSuchElementException - if there are no more to be returned.
RDFException - Generic RDF exception.
public void remove()
throws java.util.NoSuchElementException,
RDFException
remove in interface ResIteratorjava.util.NoSuchElementException
RDFException
public void close()
throws RDFException
Some implementations, e.g. on relational databases, hold resources while the iterator still exists. These will normally be freed when the iteration completes. However, if an application wishes to ensure they are freed without completing the iteration, this method should be called.
