Class NodeIteratorImpl

org.apache.xerces.dom.NodeIteratorImpl
- NodeIterator
public class NodeIteratorImpl
extends java.lang.Object
implements 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,
Node root,
int whatToShow,
NodeFilter nodeFilter,
boolean entityReferenceExpansion)
Public constructor
detach
public void detach()
getExpandEntityReferences
public boolean getExpandEntityReferences()
Return whether children entity references are included in the iterator.
getFilter
public NodeFilter getFilter()
Return the filter
getRoot
public Node getRoot()
getWhatToShow
public int getWhatToShow()
Return the whatToShow value
nextNode
public 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.
previousNode
public 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.
removeNode
public void removeNode(Node node)
Fix-up the iterator on a remove. Called by DOM or otherwise,
before an actual DOM remove.
