Description copied from interface: DocumentIterator

Closes this document iterator, releasing all resources.

You should always call this method after having finished with this iterator. Implementations are invited to call this method in a finaliser as a safety net, but since there is no guarantee as to when finalisers are invoked, you should not depend on this behaviour.
