All Implemented Interfaces:

javax.management.DynamicMBean

public class DynamicMBeanDelegator<TRECEIVER>
extends java.lang.Object
implements javax.management.DynamicMBean

An generic reflection based implementation for applying a DynamicMBean interface on a another object that actually does not need to implement the DynamicMBean interface.
