Get AnnotatedType from KType, or at least extract the annotations


#1

If I have the following class

class Item(
        id: Long? = null,
        var names: List<@Cool String> = emptyList())

How can I extract the @Cool annotation?

I tried: Item::class.memberProperties.elementAt(0).returnType which gets me a KType, but there seems to be no way to get the annotation from it? Even better, is it possible to create an AnnotatedType from a KType?

Btw, I already have a way to produce an arbitrary instance of AnnotatedType (using GeAnTyRef), so if there’s no built-in way to get an AnnotatedType from KType, I can still create it myself as long as I can get all the info I need from KType.


#2

Have you tried casting KType to KClass and calling typeParameters?


#3

The returned KTypeImpl is an instance of KTypeImpl which is not castable to KClass (and is internal).
