Examples of java.util.IdentityHashMap$EntryIterator

java.util.IdentityHashMap
Since we don't use Entry objects, we use the Iterator itself as an entry.


    Map map;
    synchronized (_suspended) {
      map = (Map)_suspended.get(desktop);
      if (map == null)
        _suspended.put(desktop, map = new IdentityHashMap(3));
          //note: we have to use IdentityHashMap because user might
          //use Integer or so as mutex
    }
    synchronized (map) {
      List list = (List)map.get(mutex);
