Interface Watcher

public interface Watcher

This interface specifies the public interface an event handler class must implement. A ZooKeeper client will get various events from the ZooKeepr 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.
