beginClassesNotificationForIF
beginClassesNotificationForIF(theClass: Class;
includeSubclasses: Boolean;
transients: Boolean;
eventType: Integer;
responseType: Integer;
eventTag: Integer;
theInterface: JadeInterface);
The beginClassesNotificationForIF method of the Object class is a variation of the beginClassesNotification method.
The beginClassesNotificationForIF 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 optionally its subclasses, rather than to those of the subscriber.
The subscriber must be an instance of a
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 beginClassesNotificationForIF method is executed.
The subscription to a notification registered by the beginClassesNotificationForIF method is terminated by the endClassesNotificationForIF method. You can also use the endNotificationForSubscriber method to terminate all notifications for a specific subscriber.
The beginClassesNotificationForIF method parameters are summarized in the following table.
| Parameter | Specifies … |
|---|---|
| theClass | The class for which the notification is to be invoked |
| includeSubclasses | Whether subclasses are included in or excluded from the notification registration |
| 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 optionally 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 beginClassesNotification method.
