Hi,

I have a class that acts as the concrete strategy for several types of context classes. In this class, I have a method implementation that delegates to one of several private methods depending on the class’s state property. I’m trying to figure out the most speed-efficient way to call the appropriate delegate methods without violating OOP design.

Right now, I’m using what I understand to be a hash look-up, such as…

[FONT=Courier New]var state:String = “foo1”;

public function facadeMethod(param1, param2):void {  
this[state](param1, param2);  
}

private function foo1(param1, param2):void {}  
private function foo2(param1, param2):void {}[/FONT]

I’m pretty sure this isn’t the best way, but the only other solution I know of is a switch statement. Because the context object will be looking for the facade method (not foo1 or foo2), I can’t simply make each method public.

Does anyone have any suggestions?
