Antoine Sabot-Durand commented on CDI-515:
------------------------------------------
I don't see that limited to instances provided by a given Instance<>. Like you
can use Instance.destroy() to destroy any instance today.
A use case could be: obtaining metadata for a bean defined by a class you don't own.
Today we store all bean instances to manage their lifecycle, so how difficult would it be
to compare a given instance with these stored instances and retrieving the bean used to
generated it. It's probably costly but could be very useful.
Allow to obtain Bean metadata from javax.enterprise.inject.Instance
-------------------------------------------------------------------
Key: CDI-515
URL: https://issues.jboss.org/browse/CDI-515
Project: CDI Specification Issues
Issue Type: Feature Request
Affects Versions: 1.2.Final
Reporter: Martin Kouba
Assignee: Martin Kouba
Fix For: 2.0 (proposed)
Sometimes it might be useful to obtain Bean metadata from the
{{javax.enterprise.inject.Instance}} (similarly as 5.5.8. Bean metadata). The method could
be named {{getBean()}} and should have similar restrictions like {{get()}} (e.g. throw
{{UnsatisfiedResolutionException}} if appropriate).
