Mark Struberg commented on CDI-420:
-----------------------------------

[~antoinesabot-durand] I thought about 'explicit' as well, but it isn't really describing what happens. See my previous comment.

Ad 'scoped' vs 'scanning' vs whatever.
I thought pretty long about it. My first take was 'explicit'. Because you have to explicitly define the classes you like to get picked up. Otoh this term doesn't define what you need to define. For example: just an @Inject somewhere would be nuts as the detection would be pretty expensive.

And this was the point which did lead me to 'scoped'. Because that's what you need to do: Define a Scope OR an annotation which leads to a defined default scope (decorator, interceptor or stereotype). Those are very easy and fast to find and have very clear rules imo.

> This is for some future CDI release.
> We currently only have 3 bean-discovery-modes
> * none
> * all
> * annotated
> The spec also currently says that ProcessAnnotatedType will only get fired (12.4) for 
> • each Java class, interface or enum deployed in an explicit bean archive, and 
> • each Java class with a bean defining annotation in an implicit bean archive. 
> • each session bean
> Which means that we do not get the ProcessAnnotatedType (PAT) event for any class in an 'annotated' or 'implicit' BDA which does _not_ have a bean defining annotation. 
> It might be useful to fire the ProcessAnnotatedType for all classes, but do not pick them up as Beans if they (after PAT) do not have a valid scope. Effectively doing the processing but not make them @Dependent automatically if there is no scope annotation at the end of the PAT processing.
> I'm not yet 100% sure how important this distinction is in practice. Just writing this up to not forget about the idea...
