[cdi-dev] [JBoss JIRA] (CDI-420) add a bean-discovery-mode 'scoped'

[Mark Struberg (JIRA)]

    [ https://issues.jboss.org/browse/CDI-420?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13200787#comment-13200787 ] 

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

We had an additional idea in a recent discussion: Keep the current bean-discovery-modes but adding another beans.xml tag or attribute in addition to bean-discovery-mode which enables this functionality.

Examples:
{quote}
<beans bean-discovery-mode="all" auto-dependent="false"> 
</beans>
{quote}
or
{quote}
<beans bean-discovery-mode="all">
    <auto-dependent>false</auto-dependent> 
</beans>
{quote}

Of course we need to discuss 
a.) whether it should be an attribute or tag
b.) the name of the attribute or tag
c.) if the logic should be 'disabling' (auto-dependent="false") or 'enabling' (only-scoped-beans="true")

> 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...
