question: public NodeSetDTM ( NodeIterator iterator , XPathContext xctxt ) { super ( ) ; Node node ; m_manager = xctxt . getDTMManager ( ) ; while ( null != ( node = iterator . nextNode ( ) ) ) { int handle = xctxt . getDTMHandleFromNode ( node ) ; addNodeInDocOrder ( handle , xctxt ) ; } }
target:  Create a NodeSetDTM, and copy the members of the given DTMIterator into it.
