39 * Interface class for objects interested in receiving events.
40 * Objects interested in events should inherit this class and implement the
41 * processEvent() method. They should then be registered with the system that
42 * they want to receive events. The system will call the processEvent() method
43 * for every installed event consumer to pass events.
