Class MBeanRegistry

java.lang.Object

org.apache.zookeeper.jmx.MBeanRegistry

public class MBeanRegistry
extends java.lang.Object

This class provides a unified interface for registering/unregistering of zookeeper MBeans with the platform MBean server. It builds a hierarchy of MBeans where each MBean represented by a filesystem-like path. Eventually, this hierarchy will be stored in the zookeeper data tree instance as a virtual data tree.

unregister

public void unregister(ZKMBeanInfo bean)

Unregister MBean.

Parameters:

bean -

unregisterAll

public void unregisterAll()
