Interface NsIterator

All Superinterfaces:

ClosableIterator, ExtendedIterator, java.util.Iterator

public interface NsIterator

extends ExtendedIterator

An iterator which returns namespace URI's.

RDF iterators are standard Java iterators, except that they have an extra method that returns a specifically typed object, in this case a String representing a namespace URI, and have a close() method that should be called to free resources if the application does not complete the iteration.
