[cdi-dev] [JBoss JIRA] (CDI-231) Clarify if Alternatives are filtered in BeanManager#getBeans() or #resolve()

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/CDI-231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12707482#comment-12707482 ] 

Martin Kouba commented on CDI-231:
----------------------------------

IMHO the spec is clear even without any changes...

{quote}
11.3.5. Obtaining a Bean by type
The method BeanManager.getBeans() returns the set of beans which _*have the given required type and qualifiers and are available for injection*_ in the module or library containing the class into which the BeanManager was injected...
{quote}

See also 5.1. Modularity and 5.1.4 Inter-module injection.

The method {{BeanManager.getBeans()}} should return all beans available for injection even those "shaded by" enabled alternatives. The method {{BeanManager.resolve()}} should only apply the ambiguous dependency resolution rules to the given set of beans. However the {{BeanManager.resolve()}} definition clarification requirement WRT CDI-227 seems legitimate.

> The spec and javadoc are not really clear if the @Alternative filter defined in "5.2.1. Unsatisfied and ambiguous dependencies" is already performed in BeanManager#getBeans() or only later in BeanManager#resolve().
> Back in 2009 I did a blind test with an old Weld version which only returned @Alternatives in getBeans() and all other beans got filtered out. This seems to have changed now (since quite some time). 
> Can we make this more clear what should happen in getBeans() and what should happen in resolve()?
