[cdi-dev] [JBoss JIRA] (CDI-45) Optional Injection Points

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/CDI-45?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13003430#comment-13003430 ] 

Martin Kouba commented on CDI-45:
---------------------------------

I don't really see any benefit from introducing any additional interface, aside from performance. And some performance issues may be partially solved by implementation.

+1 for introducing a new convenient method {{Instance.isResolved()}} (or any other better name).

> There are occoasions where it may be useful for some injection points to be optional, e.g.
> @Inject
> @Optional 
> MyBean bean; 
> This would behave the same as a normal injection point, however it will not cause the deployment to fail if it is not satisified.
