Class MBeanServerForwarder

java.lang.Object
  com.sun.jdmk.MBeanServerForwarder

All Implemented Interfaces:: MBeanServer, MBeanServerConnection

Direct Known Subclasses:: MBeanServerChecker

public class MBeanServerForwarder
extends Object
implements MBeanServer
extends Object
implements MBeanServer

An object of this class implements the MBeanServer interface and wraps another object that also implements that interface. Every method in MBeanServer is forwarded to the wrapped object.

This class is principally useful as the superclass for other wrapping classes that intercept some of the methods in MBeanServer and perform some action before forwarding to the wrapped object (or do not forward at all).

The wrapped object can be changed at any time. A frequent operation is to insert another MBeanServerForwarder between this one and the wrapped object. The idiom for that is:

 synchronized (mbeanServerForwarder) {
     MBeanServer oldmbs = mbeanServerForwarder.getMBeanServer();
     MBeanServer newmbs = new MyMBeanServerForwarder(oldmbs);
     mbeanServerForwarder.setMBeanServer(newmbs);
 }

The synchronized block ensures that information is not lost if two threads try to insert MBeanServerForwarders at the same time.

Since:: Java DMK 5.1
