Subscription closure

— associating the subscription with a closure

The subscribe method sets value of the closure originally defined as a string (in this case), My First Subscription.

p.subscribe("Sample.Intro1", new MySubscriber(),
"My First Subscription");

public void notify(Notification n, Object closure)

Upon notification delivery, the proxy passes the closure as the second argument of the notify method. The value of closure is defined by the Subscriber class.

System.out.println(
"Incoming notification for (" + closure + ")");

Incoming notification for (My First Subscription):
