接口 IZkChildListener

所有已知实现类:

AbstractListener

public interface IZkChildListener

An IZkChildListener can be registered at a ZkClient for listening on zk child changes for a given path.

Node: Also this listener re-subscribes it watch for the path on each zk event (zk watches are one-timers) is is not guaranteed that events on the path are missing (see http://zookeeper.apache.org/doc/current/zookeeperProgrammers.html#ch_zkWatches). An implementation of this class should take that into account.
