Annotation typed array values

1

  

package java.lang.annotation;



@Documented

@Retention(RetentionPolicy.RUNTIME)

@Target(ElementType.ANNOTATION_TYPE)

public @interface Target {

  ElementType value();

}


Documented

Retention(value = RetentionPolicy.RUNTIME)


// Error : Target(value = ElementType.FIELD, ElementType.CONSTRUCTOR)


// Error : Target(value = array(ElementType.FIELD, ElementType.CONSTRUCTOR))


// Error : Target(value = array<ElementType>(ElementType.FIELD, ElementType.CONSTRUCTOR))





// Error : Target(value = Array<ElementType>(ElementType.FIELD, ElementType.CONSTRUCTOR))
annotation class TestAnnotation(val a: String, val b: Int)

But, i don’t know write typed array ElementType[] value();

How to write typed array?

Kotlin sees array arguments of Java annotations as vararg automatically, try this: 

Target(ElementType.FIELD, ElementType.CONSTRUCTOR)

Thank you Alexander!

I still think array() should work in annotation parameter. See https://youtrack.jetbrains.com/issue/KT-6641 for more discussion.
