AS3 Class Function Scope

Question

If I have 2 classes and the first extends the second, how can the second class call a static function from the first?

package p1 {
    class a {
        static function a1() {
            //do soemthing
        }
    }

    class b extends a {
        static function b1() {
            //do something else
        }
    }
}

a.a1(); // this works
b.a1(); // this doesn't work
b.b1(); //this works

Answer 1

When "B extends A" - this actually is not the same as "class B has all methods and properties of A". Not class, but object of class B implements all properties and methods, defined in class A. When you call a static method or property - you deal with classes but not objects (it looks very similar to namespaces usage).

ADDED: The only way solve your task is to override a1(args) in class B and to call super.a1(args) inside... 1 string of code. But it seems to me, that you have a software architect problem if it's not possible to avoid such kind of usage.

Answer 2

Use super to call the parent method.

super.b1();

EDIT: Ok, looking at what you wrote, I think you need to set the scope of a1 to be public or protected.
