Subscriber
— the publisher's audience
In order to retrieve a notification, the application must define a subscriber class. The notify method is called whenever a notification matches the subscription.
The class MySubscriber overwrites the Notify method from the base class Subscriber:
class MySubscriber implements Subscriber
{
public void notify(Notification n,
Object closure)
};
- MySubscriber —
- application-specific class that inherits Subscriber class
- n —
- a pointer to the newly received notification
- closure —
- the closure associated with the subscription for which the notification should be delivered
