RE: [Springframework-developer] AOP API

[Kopylenko, D. <dko...@ac...>]

Well, following AspectJ terminology the Advice is the construct that
implements the crosscutting behavior (Interceptor in our case) and Aspect is
the collection of Advice and Pointcuts. But Pointcut _is not_ Advice. So,
how about:

 public interfce Advice{}
 
 public interface Interceptor extends Advice{}

 public interface Aspect {
    Advice[] getAdvice();
    Pointcut[] getPointcut();
}

Dmitriy.

Ummm...
Having a second thought, I was wrong. Advice makes sense within the AOP
terminology. If you look at AspectJ, your advice contains a pointcut *and* a
code (the interceptor part) -- the idea is that you can have abstract
pointcuts that you can then refine in subclasses of the aspects.

So, finally, I like very much:

public interface Advice {
    getInterceptor();
    getPointcut();
}

And of course the subsequent:

public interface Aspect {
    Advice[] getAdvice();
}

+1 for me.
