As you may have noticed, you can’t iterate over the properties of an Actionscript 3 class as if they were normal properties of a generic object, unless the class is dynamic of course.
here’s what I mean:
public class Widget
public var color:String = "green";
public var shape:String = "round";
public var age:String = "5";
var widget:Widget = new Widget();
for(var i:String in widget)
trace(i); // Whaaaaa? Output is blank!
Ok, so as I said.. it doesn’t work. However, there’s trick that you can use! generate an XML list of the class variables, then access them as attributes (using the above example class):
var xmlList:XMLList = flash.utils.describeType(widget)..variable;
var vars:Object = new Object();
for (var n:int; n < xmlList.length(); n++)
vars[xmlList[n]. @ name] = widget[xmlList[n]. @ name];
for (var prop:String in vars)
trace(prop); // lists: age, color. shape
I took it one step further and pushed the variables into an object called vars so that I could show iterating it as an object.
This came in really handy for me earlier today. Maybe later I’ll elaborate, but I hope that you can see the value in being able to do something like this!
