Change annotation processor dynamically

Question

Following sample is just to explain the my implementation, please have a look at and let me know if i can get any answers for this

I have created a annotation Dispenser

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
public @interface Dispenser {

}

I have two classes of type dispenser above

Milk Dispenser --

Drink Dispenser --

@Dispenser
class MilkDispenser{

    public void releaseDrink()
}

@Dispenser
class DrinkDispenser{

    public void releaseDrink()
}

and i have a class DispenserProcessor extends AbstractProcessor

Everything looks fine until unless i found a better implmentation of DispenserProcessor from the client they have their own implementation I cannot copy their code so i need a way switch to that dispenserProcessor developed by the client instead of mine

Question, is there any way @MyDispenser can extend their @ClientDispenser

Thanks Samuel, I understand as of now there is no reason of using it. So i changed my requirement a little and changed the implementation to use Dynamic proxies to solve the issue. — Maddy, Jan 17 '15 at 20:16

It seems like you would have to use annotation inheritance to support this, but annotation inheritance is not supported.

More info here: Why is not possible to extend annotations in Java?
