### addNotificationListener

    public void addNotificationListener(javax.management.ObjectName pName,
                                        javax.management.NotificationListener pListener,
                                        javax.management.NotificationFilter pFilter,
                                        java.lang.Object pHandback)
                                 throws javax.management.InstanceNotFoundException

  Description copied from interface: `JMXConnector`
  Adds the given Notification Listener in a way that the Notification Events are send back to the listener
  Please asume that the listening is terminated when the instance of these interface goes down.
  Specified by:
    `addNotificationListener` in interface `JMXConnector`
  Following copied from interface: `org.jboss.jmx.interfaces.JMXConnector`
  Parameters:
    `pBroadcasterName` - Name of the Broadcaster MBean on the remote side
    `pListener` - Local notification listener
    `pFilter` - In general there are three ways this could work: 1) A copy of the filter is send to the server but then the Filter cannot interact with the client. This is default. 2) Wrapper around the filter therefore the server sends the filter call to the client to be performed. This filter must be a subclass of RemoteNotificationListener. 3) All Notification events are sent to the client and the client performs the filtering. This filter must be a subclass of LocalNotificationListener.
    `pHandback` - Object to be send back to the listener. To make it complete transparent to the client an Object Handler is sent to the Server and and when a Notification comes back it will be looked up and send to the client. Therefore it must not be serializable.

### addNotificationListener

    public void addNotificationListener(javax.management.ObjectName pName,
                                        javax.management.ObjectName pListener,
                                        javax.management.NotificationFilter pFilter,
                                        java.lang.Object pHandback)
                                 throws javax.management.InstanceNotFoundException,
                                        java.lang.UnsupportedOperationException

  Specified by:
    `addNotificationListener` in interface `JMXConnector`
  Following copied from interface: `org.jboss.jmx.interfaces.JMXConnector`
  Throws:
    `java.lang.UnsupportedOperationException` - The MBean related to the given object cannot be wrapped by the transport layer implementation and therefore it makes no sense (no callback could be instantiated) and therefore this exception is always thrown

### removeNotificationListener

    public void removeNotificationListener(javax.management.ObjectName pName,
                                           javax.management.NotificationListener pListener)
                                    throws javax.management.InstanceNotFoundException,
                                           javax.management.ListenerNotFoundException

  Description copied from interface: `JMXConnector`
  Remoes the given Notification Listener in a way that all involved instances are removed and the remote listener is removed from the broadcaster.
  Please asume that the listening is terminated when the instance of these interface goes down.
  Specified by:
    `removeNotificationListener` in interface `JMXConnector`
  Following copied from interface: `org.jboss.jmx.interfaces.JMXConnector`
  Parameters:
    `pBroadcasterName` - Name of the Broadcaster MBean on the remote side
    `pListener` - Local notification listener

### removeNotificationListener

  Specified by:
    `removeNotificationListener` in interface `JMXConnector`
  Following copied from interface: `org.jboss.jmx.interfaces.JMXConnector`
  Throws:
    `java.lang.UnsupportedOperationException` - The MBean related to the given object cannot be wrapped by the transport layer which prevents the remove of the the wrapper and therefore it makes no sense (no callback could be instantiated) and therefore this exception is always thrown
