Mark Struberg commented on CDI-420:
-----------------------------------
With getting more and more feedback for cdi-1.1 and 1.2 in the last 2 years it became
clear that the bean-discovery-mode 'annotated' is not or less not used by
developers! Simply by the fact that not picking up interfaces and stuff create way too
many problems with Extensions. That's why I'm pushing this idea again. I just like
to rename the new bean-discovery-mode to 'scoped'.
The behaviour is the following:
1.) Scan all interfaces and classes etc just like with 'all'
2.) Fire the ProcessAnnotatedType event for all of them (just like with 'all')
3.) But for all classes in a jar or classpath entry with bean-diescovery-mode=
scoped' _only_ create Bean<T> of those AnnotatedTypes which either
* have an explicit CDI scope annotation, or
* are an Interceptor or a Decorator, or
* are a JavaEE bean, or
* have a StereoType
This will
* improve boot times
* reduce the memory footprint by not storing away tons of useless Bean<T> instances
add a bean-discovery-mode 'scoped'

Key: CDI-420
URL:
https://issues.jboss.org/browse/CDI-420
Project: CDI Specification Issues
Issue Type: Bug
Components: Packaging and Deployment
Affects Versions: TBD
Reporter: Mark Struberg
Fix For: 2.0 (discussion)
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...
