NsIteratorImpl
```
public interface NsIterator
extends ExtendedIterator<java.lang.String>
```
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.
