Detailed Description

This interface specifies the public interface an event handler class must implement.

A ZooKeeper client will get various events from the ZooKeeper server it connects to. An application using such a client handles these events by registering a callback object with the client. The callback object is expected to be an instance of a class that implements Watcher interface.

Note that the watcher is invoked by ZooKeeper from a single thread. See http://zookeeper.apache.org/doc/trunk/zookeeperProgrammers.html#C+Binding
