[weld-dev] Decorator question

[Mark Struberg]

Hi folks!

I'm a bit unsure about the interpretation of the section 8 Decorators in the spec.

There is a sentence which really confuses me:
"The set of decorated types of a decorator includes all bean types of the managed bean which are Java interfaces..."

I always thought about 2 use cases:

1.) 
@Decorator
public class MyDec1 implements AnInterface {
  @Inject @Delegate AnInterface1 theRealThing;
  ...
}

which will decorate all beans which implement the AnInterface.

2.) 
@Decorator
public class MyDec2 extends AnotherBeanClass {
  @Inject @Delegate AnotherBeanClass theRealThing;
  ...
}

which will decorate all beans which are of Type (+subclasses) of AnotherBeanClass.

This thoughts are basically backed by a few other paragraphs in the spec and also by the TCK (org.jboss.jsr299.tck.tests.lookup.injectionpoint.CatDecorator).

But for 2) the AnotherBeanClass doesn't need to implement any Interface at all (at least from the practical point of view).


txs and LieGrue,
strub
