Re: Interface Delegation or ??

I am constructing a class hierarchy where I would like to extend a
runtime determined base class.

Lets say I have an Interface, IPoint.

I implement two classes

class Point2D implements IPoint
class Point3D implements IPoint

Then, I want to create a new class, Vertex, which extends from one of
the PointND's. I don't want to have to implement two Vertex classes
(one for each PointND).

Right now, my solution is to use interface Delegation

class Vertex implements IPoint{
  protected IPoint p;
  Vertex(IPoint p){
    this.p=p;
  }
// Wrap all the IPoint methods to point to this.p

}

Is there any other syntactic mechanism to accomplish this in Java? Is
this the right way? Are there some other keywords I should search for
that I'm missing?

TIA,
