Abstract
An object-based event communications system supplies an event distribution object having an outgoing-from-publisher event interface and associated with unique identifiers defined for a publisher that is programmed to fire events by calling a method on the event distribution object's outgoing-from-publisher event interface. The event communications system stores subscriptions of subscriber objects to methods of the outgoing-from-publisher event interface. On receiving a call from a publisher to its outgoing-from-publisher interface methods, the event distribution object multi-casts calls to counterpart methods of subscriber objects that have stored subscriptions to the respective outgoing-from-publisher interface methods.
