Hi
I'm cuurrently refactoring some code in a project with lots of extended classes.
What is the recommended practice in declaring static vs non-static (private
static vs private)
variables?
Should they be declared in both the super and sub classes?
My goal is to avoid any redundant code.
Thanks
Note:
----
class SuperClass {
public static var CONSTANT:String = "SuperClass";
public function toString():String {
return CONSTANT;
}
}
----
class SubClass extends SuperClass {
public static var CONSTANT:String = "SubClass";
}
----
var obj:SubClass = new SubClass();
trace(obj.toString());
// Traces "SuperClass".

Overriding static variables does not work as you might expect. To get
this to work correctly, the variable would have to be non-static.
Other than that, you should never have to redundantly add anything to
the subclass. If the superclass and the subclass both use a string
variable called "name", just declare it in the superclass--there's no
point at all in redeclaring it in the subclass. The whole idea of
inheritance was created to avoid just that type of redundancy.
