public class NodeIteratorImpl
extends java.lang.Object
implements org.w3c.dom.traversal.NodeIterator
DefaultNodeIterator implements a NodeIterator, which iterates a
DOM tree in the expected depth first way.
The whatToShow and filter functionality is implemented as expected.
This class also has method removeNode to enable iterator "fix-up"
on DOM remove. It is expected that the DOM implementation call removeNode
right before the actual DOM transformation. If not called by the DOM,
the client could call it before doing the removal.

NodeIteratorImpl
public NodeIteratorImpl(DocumentImpl document,
org.w3c.dom.Node root,
int whatToShow,
org.w3c.dom.traversal.NodeFilter nodeFilter,
boolean entityReferenceExpansion)
Public constructor
detach
public void detach()
- detach in interface org.w3c.dom.traversal.NodeIterator
getExpandEntityReferences
public boolean getExpandEntityReferences()
Return whether children entity references are included in the iterator.
- getExpandEntityReferences in interface org.w3c.dom.traversal.NodeIterator
getFilter
public org.w3c.dom.traversal.NodeFilter getFilter()
Return the filter
- getFilter in interface org.w3c.dom.traversal.NodeIterator
getRoot
public org.w3c.dom.Node getRoot()
- getRoot in interface org.w3c.dom.traversal.NodeIterator
getWhatToShow
public int getWhatToShow()
Return the whatToShow value
- getWhatToShow in interface org.w3c.dom.traversal.NodeIterator
nextNode
public org.w3c.dom.Node nextNode()
Return the next Node in the Iterator. The node is the next node in
depth-first order which also passes the filter, and whatToShow.
If there is no next node which passes these criteria, then return null.
- nextNode in interface org.w3c.dom.traversal.NodeIterator
previousNode
public org.w3c.dom.Node previousNode()
Return the previous Node in the Iterator. The node is the next node in
_backwards_ depth-first order which also passes the filter, and whatToShow.
- previousNode in interface org.w3c.dom.traversal.NodeIterator
removeNode
public void removeNode(org.w3c.dom.Node node)
Fix-up the iterator on a remove. Called by DOM or otherwise,
before an actual DOM remove.
