Interface NotificationHandlerDelegate

All Known Implementing Classes:

ContextCaptureDelegate, RequestCaptureDelegate

public interface NotificationHandlerDelegate

Custom delegate interface for use with NotificationHandlerMBean via NotificationHandlerDelegateFactory implementations.

Supported API: true

Extendable: true

Method Summary

void	postHandleNotification() Method called by NotificationHandlerMBean both upon receipt of notification and when computing the InfoItemsPreview attribute (via getInfoItemsPreview()).
boolean	preHandleNotification(NotificationHandlerMBean mbean, ObjectName source, Notification notification, boolean willOutputInfo) Method called by NotificationHandlerMBean both upon receipt of notification and when computing the InfoItemsPreview attribute (via getInfoItemsPreview()).

Method Detail

preHandleNotification

boolean preHandleNotification(NotificationHandlerMBean mbean,
                              ObjectName source,
                              Notification notification,
                              boolean willOutputInfo)

Method called by NotificationHandlerMBean both upon receipt of notification and when computing the InfoItemsPreview attribute (via getInfoItemsPreview()). In both cases, this method is called prior to any retrieval of JMX attribute data for output purposes.

Supported API: true

Parameters:

mbean - NotificationHandlerMBean from which this delegate is being called

source - Source of notification; may be null when called from getInfoItemsPreview()

notification - Notification object; will be null when called from getInfoItemsPreview() and non-null otherwise

willOutputInfo - Whether the NotificationHandlerMBean would produce output on its own

Returns:

Whether NotificationHandlerMBean should still produce output; result is ignored when called from getInfoItemsPreview()

postHandleNotification

void postHandleNotification()

Method called by NotificationHandlerMBean both upon receipt of notification and when computing the InfoItemsPreview attribute (via getInfoItemsPreview()). In both cases, this method is called after any retrieval of JMX attribute data for output purposes.

Note that this will be the same instance of this class upon which the corresponding preHandleNotification() call was made and that separate instances are used otherwise -- so one can place data in the instance in preHandleNotification() for use in this routine.
