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! -- Zhu Chenjie Zhejiang University, China
