Class ListenerIterator

java.lang.Object
  org.zkoss.zk.ui.impl.ListenerIterator

All Implemented Interfaces:

java.util.Iterator

public class ListenerIterator
extends java.lang.Object
implements java.util.Iterator

Used to iterate the event listener.

It resolves a bug of LinkedList: LinkedList's hasNext() and hasPrevious() doesn't check concurrent-modification. Thus, if the 2nd last listener is removed, hasNext() simply return false (and the last listener is ignored) rather than throwing ConcurrentModificationException. Refer to Bug 1730532.
