Paul King updated GROOVY-7814:
------------------------------
Description:
This feature suggestion is proposing to extend the allowable return types for
members in annotation definitions.
{code}
import java.lang.annotation.*
@Retention(RetentionPolicy.RUNTIME)
@Target([ElementType.TYPE])
@interface AnyAnnotationCollection {
Annotation[] value()
}
{code}
In this example, Java would require a specific annotation class instead of just
{{Annotation}}.
Usage of the above annotation definition would look like:
{code}
@AnyAnnotationCollection([
@Grab('foo:bar:1.0'),
@AnyAnnotationCollection([
@FunctionalInterface,
@Deprecated
])
])
class Dummy{}
assert Dummy.annotations[0].value().size() == 2
assert Dummy.annotations[0].value()[1].value()[0].annotationType().simpleName
== 'FunctionalInterface'
{code}
The nesting here is not in any way required but supported.
> Consider allowing Groovy to support Arrays of arbitrary annotations as the
> return type of an annotation definition member
