Can I use "Declare Parents" to make an interface be the parent of another interface?

[João Gonçalves-3]

Greetings.

Can I use @DeclareParents this way:


interface A { }

interface B { }

@DeclareParents(value="B", defaultImpl=BImpl.class)
private A something;

class C implements A { }




Will class C have the methods declared in B?

Does this do what you want?


interface A { }

interface B { void foo();}

class BImpl implements B { public void foo() {System.out.println("foo
running");}}

@Aspect
class X {
       
        @DeclareMixin("C")
        public static B createB() {
                return new BImpl();
        }
               
        public static void main(String[] args) {
                ((B)new C()).foo();
        }
}

class C implements A { }

What I wanted to know was if declaring an implementation for an interface, automatically declared the implementation for the implementing classes. But the answer is no.

I've filed an enhancement request (as suggested by other users): https://bugs.eclipse.org/bugs/show_bug.cgi?id=288713

Thanks.
