As I mentioned in my last post, the Delegate class is quite useful even if I couldn’t pass parameters as easily as I would have wanted. While looking around today, I stumbled on this method which makes things much easier. I don’t like how it’s written because of the in-line functions, but it really does solve the problem. Here’s the code, which I took the liberty to customize a little bit:
class Utils {
// Desc : Usually, when you attach a functio nto an event, you can't pass
// parameters, using this function instead of the Delegate class
// will allow you to do the same thing but with unlimitted parameters
// Window: General Information.
// http://www.person13.com/articles/proxy/Proxy.htm
public static function delegateEvent(oTarget:Object, fFunction:Function):Function {
// Create an array of the extra parameters passed to the method. Loop
// through every element of the arguments array starting with index 2,
// and add the element to the aParameters array.
var aParameters:Array = new Array();
for(var i:Number = 2; i < arguments.length; i++) {
aParameters[i - 2] = arguments[i];
}
// Create a new function that will be the proxy function.
var fProxy:Function = function():Void {
var aActualParameters:Array = arguments.concat(aParameters);
fFunction.apply(oTarget, aActualParameters);
};
return fProxy; }
}And you can call it like this:
private function someFunction():Void {
this._xml.onLoad = Utils.delegateEvent(this, xml_onLoad, "GeneralInformation");
}
private function xml_onLoad(success:Boolean, nextStep:String):Void {
if(success)
// Get the contents of xml
switch (nextStep) {
case "GeneralInformation" :
this.open_GeneralInformation();
break;
//etc...
}
}It really saved me time.
