EventListenerSource
EventSupport provides simple access to events.
To apply event abilities to your class its only necessary to extend
EventSupport. It holds in the private instance variable
distributorControl a reference to
SimpleConsumableCompositeEventDistributionControl.
To allow additional listener types to be checked by addListener,
addAddListener its only necessary to add acceptListenerType(AnyType);
within the constructor of the extended class.
It is necessary for sending a event to recieve the matching distributor with
distributorControl.getDistributor(AnyType) and execute the event to it.
Example code:
class Controller extends EventSupport {
private var model:Model;
private var distributor:View;
public function Controller(Void) {
distributorControl.acceptListenerType(View);
distributor = distributorControl.getDistributor(View);
}
public function setTargetModel(model:Model) {
this.model = model;
distributor.onTargetModelChanged(this);
}
public function getTargetModel(Void):Model {
return model;
}
}
new EventSupport()public function addListener(listener):Void
Adds the passed-in listener to be executed by events.
listener | the listener to add |
| IllegalArgumentException | if the listener does not match any expected type |
public function addAllListeners(listeners:Array):Void
Adds all listener contained in the passed-in listeners array.
All listeners get added after each other. If one listener does not match any expected type the rest of the listeners will not be added an a exception will raise.
