AsBroadcaster 269
Parameters
obj:Object - An object to serve as a broadcasting object.
Example
The following example creates a generic object,
someObject, and turns it into an event
broadcaster. The output should be the strings shown in the two
trace() statements:
var someObject:Object = new Object(); // Creates broadcast object.
var myListener1:Object = new Object(); // Creates listener object.
var myListener2:Object = new Object(); // Creates listener object.
myListener1.someEvent = function() { // Creates listener method.
trace("myListener1 received someEvent");
}
myListener2.someEvent = function() { // Createz listener method.
trace("myListener2 received someEvent");
}
AsBroadcaster.initialize(someObject); // Makes someObject an event
broadcaster.
someObject.addListener(myListener1); // Registers myListener1 as listener.
someObject.addListener(myListener2); // Registers myListener2 as listener.
someObject.broadcastMessage("someEvent"); // Broadcasts the "someEvent"
message.
The following example shows how to pass extra arguments to a listener method by using the
broadcastMessage() method. The output should be the three strings shown in the three
trace() statements, which also include the arguments passed in through the
broadcastMessage() method.
var someObject:Object = new Object();
var myListener:Object = new Object();
myListener.someEvent = function(param1:Number, param2:String) {
trace("myListener received someEvent");
trace("param1: " + param1);
trace("param2: " + param2);
}
AsBroadcaster.initialize(someObject);
someObject.addListener(myListener);
someObject.broadcastMessage("someEvent", 3, "arbitrary string");
