The reason is that I’m writing a helper method for JNI methods. I need the signature of a method, so I am using reified generics in an inline method for this. I can check T::class against Int::class, Double::class, etc to get the proper signature. I can’t check against jstring/jobject, however, since both are typedefs for CPointers.

Is there a performance hit due to reflection? I should mention this is K/N, so I don’t know as much about reflection on K/N.

I tried using a when with typeOf, but when I pass in a typeOf a typedef, it always triggers the when branch with the first type that has the same underlying class. If I have

when(type) {
    typeOf<jstring> -> "String"
    typeOf<jobject> -> "Object"
}

and pass in typeOf<jobject>, it returns “String”

where jstring and jobject are both typedefs for CPointer
