Method Detail

getZk

protected IZooKeeper getZk()

Specified by:

getZk in class AbstractZooKeeper

chroot

public IZKClient chroot(java.lang.String path)

Specified by:

chroot in interface IZKClient

Returns:

a new client with the path that has been chrooted... meaning all paths will be relative to the path provided.

isConnected

public boolean isConnected()

Specified by:

isConnected in interface IZKClient

Returns:

true if connected

registerListener

public void registerListener(LifecycleListener listener)

Registers a listener for lifecycle management. Due to the nature of ZooKeeper, you should always register a listener and act appropriately on the 2 events that you can receive. Note that it is guaranteed that the listener will be called even if the connection with ZooKeeper has been established a while ago...

Specified by:

registerListener in interface IZKClient

Parameters:

listener - the listener

removeListener

public void removeListener(LifecycleListener listener)

Removes a listener previously set with IZKClient.registerListener(LifecycleListener)

Specified by:

removeListener in interface IZKClient
