[cdi-dev] Accepting class type for simple (qualifier) annotations in APIs?

[arjan tijms]

Hi,

Annotation builder would be +1. It's a tiny bit less convenient, but more
universal. So better for the spec.

Convenience addition could theoretically still be:

Set<Bean<?>> getBeans(Type beanType, Class<?> annotationType, Object...
annotation attributes);

But... I acknowledge that  this would again be for a more specific
situation (namely, a bean with exactly 1 qualifier and 0 or more binding
attributes).

While on the subject, it's currently not possible for an injected bean to
get hold of the annotation instance that's used in CDI.current().select(),
BeanManager.getBeans, etc, is it?

Kind regards,
Arjan Tijms
