How to expose a method in an interface without making it public to all classes

Question

I have a issue where I\'m working with a particular interface for quite a lot of things. However, I have a particular method that I want to be available only to a particular

Answer 1

Today I've encountered same problem. Fortunately I had opportunity to make a superclass instead of interface. Instead of using this:

internal interface IPhysicalObject extends IIDObject {

    function get shape():IShape;

}

I wrote this:

public class PhysicalObject extends IDObject {

    public function PhysicalObject():void {

        ...

    }

    internal function get shape():IShape { ... }

}

Of course it's only possible if classes that implement IPhysicalObject interface do not extend any other class. I think that is another possible solution.
