public class NodeIteratorImpl
extends java.lang.Object
implements org.w3c.dom.traversal.NodeIterator
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.

Public constructor
|
| Modifier and Type | Method and Description |
|---|---|
void |
detach()
Detaches the
NodeIterator from the set which it iterated
over, releasing any computational resources and placing the
NodeIterator in the INVALID state. |
boolean |
getExpandEntityReferences()
Return whether children entity references are included in the iterator.
|
org.w3c.dom.traversal.NodeFilter |
getFilter()
Return the filter
|
org.w3c.dom.Node |
getRoot()
The root node of the
NodeIterator, as specified when it
was created. |
int |
getWhatToShow()
Return the whatToShow value
|
org.w3c.dom.Node |
nextNode()
Return the next Node in the Iterator.
|
org.w3c.dom.Node |
previousNode()
Return the previous Node in the Iterator.
|
void |
removeNode(org.w3c.dom.Node node)
Fix-up the iterator on a remove.

detach has been invoked, calls to nextNode
or previousNode will raise the exception
