question: public void dispatchToEvents ( int nodeHandle , org . xml . sax . ContentHandler ch ) throws org . xml . sax . SAXException { TreeWalker treeWalker = m_walker ; ContentHandler prevCH = treeWalker . getContentHandler ( ) ; if ( null != prevCH ) { treeWalker = new TreeWalker ( null ) ; } treeWalker . setContentHandler ( ch ) ; try { Node node = getNode ( nodeHandle ) ; treeWalker . traverseFragment ( node ) ; } finally { treeWalker . setContentHandler ( null ) ; } }
target:  Directly create SAX parser events from a subtree.
