[cdi-dev] [JBoss JIRA] (CDI-231) Clarify if Alternatives are filtered in BeanManager#getBeans() or #resolve()
[
https://issues.jboss.org/browse/CDI-231?page=com.atlassian.jira.plugin.sy...
]
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.
Clarify if Alternatives are filtered in BeanManager#getBeans() or
#resolve()

Key: CDI-231
URL: https://issues.jboss.org/browse/CDI-231
Project: CDI Specification Issues
Issue Type: Clarification
Components: Resolution
Affects Versions: 1.0, 1.1.EDR1
Reporter: Mark Struberg
Assignee: Pete Muir
Fix For: 1.1 (Proposed)
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()?
