John Ament commented on CDI-45:
-------------------------------
[~mkouba] I think the implication is that we want some of the features of {{Optional}}. For example
{code}
MyBean bean = instance.select(MyBean.class).orElseThrow(() -> SomeException.class);
MyBean bean = instance.select(MyBean.class).orElse(someAlternate); //or supply
instance.select(MyBean.class).ifPresent(() -> someWork);
{code}
> Optional Injection Points
> -------------------------

> Key: CDI-45
> URL: https://issues.jboss.org/browse/CDI-45
> Project: CDI Specification Issues
> Issue Type: Feature Request
> Components: Resolution
> Affects Versions: 1.0
> Reporter: Stuart Douglas
> Priority: Optional
> Fix For: TBD
>
>
> 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.
