public interface ServiceListener
An interface for objects that respond to service operations.
A service listener implements only two methods for handling any type of service operation. This decouples the listener interface and implementations from the set of events published by the various services. Listeners should be coded to respond to only the events they care about, as distinguished by an event's id.
