copied!<p>I think you are asking if a class instance can implement addEventListener() and dispatchEvent() like a DOM element. If the class is not a DOM node, then you would have to write your own event bus. You would define an interface for a class that can publish events, then implement the interface in the your classes. Here is a naive example;</p> <pre><code>interface IEventDispatcher{ // maintain a list of listeners addEventListener(theEvent:string, theHandler:any); // remove a listener removeEventListener(theEvent:string, theHandler:any); // remove all listeners removeAllListeners(theEvent:string); // dispatch event to all listeners dispatchAll(theEvent:string); // send event to a handler dispatchEvent(theEvent:string, theHandler:any); } class EventDispatcher implement IEventDispatcher { private _eventHandlers = {}; // maintain a list of listeners public addEventListener(theEvent:string, theHandler:any) { this._eventHandlers[theEvent] = this._eventHandlers[theEvent] || []; this._eventHandlers[theEvent].push(theHandler); } // remove a listener removeEventListener(theEvent:string, theHandler:any) { // TODO } // remove all listeners removeAllListeners(theEvent:string) { // TODO } // dispatch event to all listeners dispatchAll(theEvent:string) { var theHandlers = this._eventHandlers[theEvent]; if(theHandlers) { for(var i = 0; i < theHandlers.length; i += 1) { dispatchEvent(theEvent, theHandlers[i]); } } } // send event to a handler dispatchEvent(theEvent:string, theHandler:any) { theHandler(theEvent); } } </code></pre>
