Detailed Description

Subscriber can subscribe to a monitor by registering a predicate with a class type of events.

When an event is triggered, then for every predicate satisfied by the event, the subscriber is notified (triggered). For every subscriber having registered the class event type that match this event, the subscriber is also triggered. A subscriber is only triggered once whatever is the way it has defined its subcription.
