PHP Класс Event_Dispatcher, newscoop

The Event_Dispatcher acts acts as a notification dispatch table. It is used to notify other objects of interesting things, if they meet certain criteria. This information is encapsulated in {@link Event_Notification} objects. Client objects register themselves with the Event_Dispatcher as observers of specific notifications posted by other objects. When an event occurs, an object posts an appropriate notification to the Event_Dispatcher. The Event_Dispatcher dispatches a message to each registered observer, passing the notification as the sole argument. The Event_Dispatcher is actually a combination of three design patterns: the Singleton, {@link http://c2.com/cgi/wiki?MediatorPattern Mediator}, and Observer patterns. The idea behind Event_Dispatcher is borrowed from {@link http://developer.apple.com/documentation/Cocoa/Conceptual/Notifications/index.html Apple's Cocoa framework}.
