User Notifications

User notifications enable you to send application-specific events that are outside the scope of the events for which system notifications are sent. For example, a form in an application may want to send a notification in response to a button being clicked.

To cause a user notification, a method uses the Object class causeEvent, sdeCauseEvent, or sdsCauseEvent method to inform the JADE Object Manager that the event has occurred. The JADE Object Manager then sends the notification to all objects that have registered an interest in it. For details about Synchronized Database Service (SDS) events and notifications, see "Persistent Events and Notifications", in Chapter 10.
