Class MBeanRegistrationListener

java.lang.Object

org.glassfish.admin.amx.util.jmx.NotificationListenerBase

org.glassfish.admin.amx.util.jmx.MBeanRegistrationListener

All Implemented Interfaces:

EventListener, NotificationListener

public abstract class MBeanRegistrationListener
extends NotificationListenerBase

Convenience base class for listening to MBeanServerNotification notifications. A class extending this class must implement mbeanRegistered(javax.management.ObjectName) and mbeanUnregistered(javax.management.ObjectName).

The class is designed to start listening upon creation. The caller should call cleanup() when listening is no longer desired. Once cleanup() is called, no further listening can be done; a new MBeanRegistrationListener should be instantiated if further listening is desired.

Constructor Detail

MBeanRegistrationListener

protected MBeanRegistrationListener(String name,
                                    MBeanServerConnection conn,
                                    ObjectName constrain)
                             throws IOException

If 'constrain' is non-null, then all registration and unregistration events will be filtered through it. Only those MBeans matching will be passed through to mbeanRegistered(javax.management.ObjectName) and mbeanUnregistered(javax.management.ObjectName).

Parameters:

conn -

constrain - optional fixed or pattern ObjectName

Throws:

IOException

MBeanRegistrationListener

protected MBeanRegistrationListener(String name,
                                    MBeanServerConnection conn)
                             throws IOException

Calls this( conn, null ).

Parameters:

conn -

Throws:

IOException
