Examples of org.apache.zookeeper.Watcher

org.apache.zookeeper.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.

        try
        {
            client.create().forPath("/sessionTest");


            final AtomicBoolean sessionDied = new AtomicBoolean(false);
            Watcher watcher = new Watcher()
            {
                @Override
                public void process(WatchedEvent event)
                {
                    if ( event.getState() == Event.KeeperState.Expired )
