             Summary: Add some built in predicates
                 Key: CDI-605
                 URL: https://issues.jboss.org/browse/CDI-605
             Project: CDI Specification Issues
          Issue Type: Feature Request

            Reporter: John Ament


During review, Antonin pointed out some useful predicates that should be reusable in the context of CDI.

{code}
    static Predicate<Bean> hasType(Type type) {
        requireNonNull(type);
        return bean -> bean.getTypes().contains(type);
    }

    static Predicate<Annotation> isAnnotationType(Class<? extends Annotation> clazz) {
        requireNonNull(clazz);
        return annotation -> clazz.equals(annotation.annotationType());
    }
{code}

We should consider adding them.
