SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
java.lang.Object | +--gnu.xml.dom.DomIterator
"NodeIterator" implementation, usable with any L2 DOM which supports MutationEvents.
Constructor Summary | |
protected |
DomIterator(Node root,
int whatToShow,
org.w3c.dom.traversal.NodeFilter filter,
boolean entityReferenceExpansion)
Constructs and initializes an iterator. |
Method Summary | |
void |
detach()
DOM L2 Flags the iterator as done, unregistering its event listener so that the iterator can be garbage collected without relying on weak references (a "Java 2" feature) in the event subsystem. |
boolean |
getExpandEntityReferences()
DOM L2 Returns the flag controlling whether iteration descends through entity references. |
org.w3c.dom.traversal.NodeFilter |
getFilter()
DOM L2 Returns the filter provided during construction. |
Node |
getRoot()
DOM L2 Returns the root of the tree this is iterating through. |
int |
getWhatToShow()
DOM L2 Returns the mask of flags provided during construction. |
void |
handleEvent(Event e)
Not for public use. |
Node |
nextNode()
DOM L2 Returns the next node in a forward iteration, masked and filtered. |
Node |
previousNode()
DOM L2 Returns the next node in a backward iteration, masked and filtered. |

public void handleEvent(Event e)
This version works by watching removal events as they bubble up. So, don't prevent them from bubbling.
handleEvent
in interface EventListener
org.w3c.dom.events.EventListener
evt
- The Event
contains contextual information
about the event. It also contains the stopPropagation
and preventDefault
methods which are used in
determining the event's flow and default action.
