Idea on "write only implementation" for control

[Ias]

Hi all,

While I was writing a control part in my article, I felt that "why not just
coding an implementation?". For example, in control tutorial

package hellocontrol; 

import org.apache.beehive.controls.api.bean.*;

@ControlImplementation(pairedInterface="hellocontrol.Hello")
public class HelloImpl implements Hello
{ 
    public String hello()
    {
        return "Hello, World!";
    }
}

leads to generate

package hellocontrol; 

import org.apache.beehive.controls.api.bean.ControlInterface;

@ControlInterface
public interface Hello
{ 
    public String hello();
}

It seems obvious that in many (simple) cases an interface for a control is a
duplicate from an implementation in terms of method declaration.

What do you think of this?
