Reload a method during a variable change

Question

I want to run a method when a variable changes.. Some sort of
listener on the variable.. Something like that.. Is it possible?
Any ideas?

Answer 1

One way to do this is to use a setter function. to the
outside, it looks just like a variable, but is really a function in
which you can do whatever you want. It has a special format:
[Bindable]private var _sMyString:String;
public function set myString(sValue:String):void {
_sMyString = sValue; //normal variable stuff
//now do whatever special processing you need to do.
Use this property like this
myString = "someValue";
or:
this.myString = "someValue";
or
myClass.myString = "someValue";
You can also look into changeWatcher()
