Interface NotificationBroadcaster

Known Subinterfaces:
NotificationEmitter
Known Implementing Classes:
MBeanServerDelegate, NotificationBroadcasterSupport
public interface NotificationBroadcaster
Represents a bean that can emit notifications when events occur. Other beans can use this interface to add themselves to the list of recipients of such notifications.

Note: New classes should use NotificationEmitter, a subinterface of this, in preference to using this interface directly.

Since:
1.5

Method Summary

void
addNotificationListener(NotificationListener listener, NotificationFilter filter, Object passback)
Registers the specified listener as a new recipient of notifications from this bean.
MBeanNotificationInfo[]
getNotificationInfo()
Returns an array describing the notifications this bean may send to its registered listeners.
void
removeNotificationListener(NotificationListener listener)
Removes the specified listener from the list of recipients of notifications from this bean.

Method Details

addNotificationListener

public void addNotificationListener(NotificationListener listener,
                                    NotificationFilter filter,
                                    Object passback)
            throws IllegalArgumentException
Registers the specified listener as a new recipient of notifications from this bean. If non-null, the filter argument will be used to select which notifications are delivered. The supplied object will also be passed to the recipient with each notification. This should not be modified by the broadcaster, but instead should be passed unmodified to the listener.
Parameters:
listener - the new listener, who will receive notifications from this broadcasting bean.
filter - a filter to determine which notifications are delivered to the listener, or null if no filtering is required.
passback - an object to be passed to the listener with each notification.
Throws:
IllegalArgumentException - if listener is null.

removeNotificationListener(NotificationListener)

getNotificationInfo

public MBeanNotificationInfo[] getNotificationInfo()
Returns an array describing the notifications this bean may send to its registered listeners. Ideally, this array should be complete, but in some cases, this may not be possible. However, be aware that some listeners may expect this to be so.
Returns:
the array of possible notifications.

removeNotificationListener

public void removeNotificationListener(NotificationListener listener)
            throws ListenerNotFoundException
Removes the specified listener from the list of recipients of notifications from this bean. This includes all combinations of filters and passback objects registered for this listener. For more specific removal of listeners, see the subinterface NotificationEmitter.
Parameters:
listener - the listener to remove.
Throws:
ListenerNotFoundException - if the specified listener is not registered with this bean.
