It's a CDI defined interface.

- you could also use the create() method to make an instance.

Yes, my bad.

Yes. Can you propose an alternative structure, as I guess you have a
similar structure in EJB?
That means we'll need both component-level and per-method lists. I
don't see
the benefit of this approach. Why not just register a single CDI
impl interceptor
that knows about all the CDI-specific application interceptors? The
ejb container
will register it in the right place in the chain and it can delegate
all the
@PostConstruct , @AroundInvoke, etc. methods appropriately. If the
interceptor instance
itself needs some context we can agree on a constructor argument such as
EjbDescriptor.

We can call it anytime during or after the deployBeans() phase of
bootstrap. Is that early enough? When would be best?
