array by calls to the

Example
The following example shows how to use the
listener objects currently registered to an event broadcaster. The following code works if it is
added to the first full example in the Examples section of the
entry:
trace(someObject._listeners.length); // Output: 2
For advanced users, the following example shows how to use the
all of the listeners registered with an event broadcaster, along with all of the properties of each
listener object. The following example creates two different listener methods for the first
listener object.
var someObject:Object = new Object(); // create broadcast object
var myListener1:Object = new Object(); // create listener object
var myListener2:Object = new Object(); // create listener object
myListener1.someEvent = function() { // create listener method
trace("myListener1 received someEvent");
}
myListener1.anotherEvent = function() { // create another listener method
trace("myListener1 received anotherEvent");
}
myListener2.someEvent = function() { // create listener method
trace("myListener2 received someEvent");
}
AsBroadcaster.initialize(someObject); // make someObject an event
broadcaster
someObject.addListener(myListener1); // register myListener1 as listener
someObject.addListener(myListener2); // register myListener2 as listener
var numListeners:Number = someObject._listeners.length; // get number of
registered listeners
