[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=13305826#comment-13305826 ] 

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

-1 for adding those methods on {{Instance}} and -1 for introducing {{Optional}} built-in bean (mainly due to serialization issues and the need for special handling, e.g. disallow programatic lookup). {{Instance.getOptional().ifPresent(...)}} etc. is imho easier to understand.

> 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.
