get hold of annotations while inside a @Provides method

[Bert Robben]

Hi,

Is it possible to get hold of annotations on the injection point inside a provider ?

To make this more clear, I'd like to do the following, 

Given a number of service classes:

class A { @Named("B") X x; ... }

class B { @Named("C") X x;... }

class C { ... }

...

And this module:

public class MyModule extends AbstractModule {

@Provides

@Named("A")

public X a(Injector inj) {

return createX(inj.getProvider(A.class)));

}

@Provides

@Named("B")

public X b(Injector inj) {

return createX(inj.getProvider(B.class)));

}

@Provides

@Named("C")

public X c(Injector inj) {

return createX(inj.getProvider(C.class)));

}

...

@Override

protected void configure() {

}

        protected X createX(...) {

             return ...;

        }

}

but then without all the duplication of the providers. So ideally I'd like to have this @Named() annotation as a parameter to the provider method.

So something like:

@Provides

public X createX(Y y, Injector inj) { // no idea what this Y would be

                String name = getValueOfNamedAnnotation(y);

return createX(inj.getProvider(getImplementationClassFor(y))));

}

Is that possible?

thanks,

Bert
