About as3-signal

Signal available  in As3 signals
Signals are light-weight, strongly-typed AS3 messaging tools.
(i)A Signal is essentially a mini-dispatcher specific to one event, with its own array of listeners.
(ii) Listeners subscribe to real objects
(iii)Signals are inspired by C# events and signals/slots in Qt.

var created:Signal = new Signal()
Remove all event handlers with one convenient method:
created.removeAll();
Retrieve number of listeners:
created.numListeners;
Add a listener that will be removed automatically after just one event:
created.addOnce(theListener); // result: signal has one listener
created.dispatch(theEvent);   // result: by Usinf the addonce listencer , if we dispatched the events soo many time
it will dispatch once only

1.Signal
2.DeluxeSignal
3.NativeSignal

Signal :
Creates a Signal instance to dispatch value objects.
@paramValueClasses Any number of class references that enable type checks in dispatch().
we can pass the N number of valueClasses as argument
for example :
var testedSignal:Signal = new Signal(String, int);
testedSignal.add(getDetails);
testedSignal.dispatch(“firstString”,1)
//testedSignal.dispatch()// will throw ArgumentError
//testedSignal.dispatch(‘firstString’,.25)// will throw ArgumentError

public function getDetails( str1:String , Num:Number) :void
{
trace(str1+”====”+Num)
}

DeluxeSignal :
DeluxeSignal(target:Object, …valueClasses)
@param the signal will dispatching the target object and value classes
For eg,
var dispatchedDeluxe:DeluxeSignal = new DeluxeSignal(this)
dispatchedDeluxeadd(deluxeTest);
dispatchedDeluxe.dispatch(this,”hello”);
public function deluxeTest(obj:Object, str:String) :void
{
// you will get the traget object , were we fires the signal
trace(obj+”==”+str)
}
Native Signal
NativeSignal(target:IEventDispatcher, eventType:String, eventClass:Class = null)
@ target object
@ eventType The type of Event permitted to be dispatched from this signal
@ eventClass An optional class reference that enables an event type check in dispatch()
for eg,
// singnalDemoClass
public var click:NativeSignal
public class testing extends Sprite {
click = new NativeSignal(this, MouseEvent.CLICK, MouseEvent);
with (this.graphics){
beginFill(0x000000);
drawRect(0, 0, 50, 50);
endFill();
beginFill(0xFFFFFF);
drawRect(10, 10, 10, 10);
drawRect(30, 10, 10, 10);
drawRect(10, 30, 30, 10);

}
// main class
demoAs.click.add(onClick);
private function onClick(event:MouseEvent) : void {
// whenever user trigger the button the signal will dispatched here
}
