Subject when to callback processResult
Date Tue, 12 Jul 2011 05:30:31 GMT
Hi, everyone:
   I'm new to zookeeper. I'm now reading through some demo and feel a little
confused about the "Watcher". The code is:

   zk.exists(znode, true, this, null);

   so now I have two callback: *process(WatchedEvent event)* which is for
Watcher and *processResult(int rc, String path, Object ctx, Stat stat)* which
is for AsyncCallback.StatCallback. So I want to know what's the difference
of these two callback and when they will be called? I can't find answers in
API. Thanks!
