beginClassNotificationForIF

beginClassNotificationForIF(theClass:     Class;
                            transients:   Boolean;
                            eventType:    Integer;
                            responseType: Integer;
                            eventTag:     Integer;
                            theInterface: JadeInterface);

The beginClassNotificationForIF method of the Object class is a variation of the beginClassNotification method.

The beginClassNotificationForIF method allows notification events to be sent to methods mapped to the userNotification and sysNotification methods of the theInterface parameter when a nominated event occurs on instances of a class and its subclasses, rather than to those of the subscriber.

The subscriber must be an instance of a Class that includes methods that map to (implement) the specified sysNotification or userNotification method of the interface. The parameters specified in the method signatures must match the standard userNotification or sysNotification method, as follows.

sysNotification(eventType: Integer; theObject: Object; eventTag: Integer);

userNotification(eventType: Integer; theObject: Object; eventTag: Integer;                  userInfo: Any);

If the method signature does not match the standard userNotification or sysNotification method, an exception is raised when the beginClassNotificationForIF method is executed. The request for a notification registered by the beginClassNotificationForIF method is terminated by the endClassNotificationForIF method. You can also use the endNotificationForSubscriber method to terminate all previous notifications for a specified subscriber.

The beginClassNotificationForIF method parameters are summarized in the following table.

Parameter	Specifies…
theClass	The interface implementation class for which the notification is to be invoked
transients	If the user notification is invoked for events occurring in transient instances
eventType	The type of event for which the notification is requested
responseType	The frequency with which an event notification is sent
eventTag	An integer value that is required for each notification
theInterface	The interface implemented by the specified class and its subclasses

For details about the other parameters with the exception of the theInterface parameter described in the following subsection, see the appropriate subsections of the beginClassNotification method.
