Flash, ActionScript 3: define a variable as a variable from its creator without constantly using creator.var ....

Question

Hi,

I am trying to split up my code in classes. but there is a issue what really bothers me. when i create a class for functions i am giving its own stage. like this

dragf:Dragfunctions = new Dragfunctions(this)

and in the class i use this

var stage:Object;

    public function Dragfunctions(stage:Object) 
    {
            this.stage = stage;
    }

as you can see i can now call a variable of the stage using stage.var1 = "hi" but when i need to ajust that varable many times it gets a quite messy...

there is a way to tell that when i call var1 he knows i mean stage.var1 without need to call stage. its:

var var1 = stage.var1 

and then using

stage.var1 = var1 

but that is quite unhandy too is there a better way?

Yes, use getters and setters (which provide field-like semantics, but allow you to execute custom logic when assignment is used):

function set var1(val:SomeType):void
{
    stage.var1=val;
}
function get var1():SomeType
{
    return stage.var1;
}
function doStuff():void
{
    var1=new SomeType();  //this results in call to "set" method
    var st:SomeType=var1; //this results in call to "get" method
}
