is there a way to construct an instance of KClass<Foo<Bar>> if all I have is an instance of KClass<Bar>?

And just in case I'm on the wrong track entirely, here's what I want to do

fun <T : Any> map(data : SomeData, type: KClass<T>) : Foo<T> = objectMapper.readValue(objectMapper.writeValueAsString(data), my-instance-of-kclass<Foo<type>>)

and then the method would be called with map(data, Bar::class). And of course I could use reified/inline function and then the second argument to readValue would be Foo<T> but I want the non-reified version of it 😉

KClass<Foo<Bar>> and KClass<Bar> are completely different values - KClass<Foo<Bar>> is really just KClass<Foo<*>>. KCLasses don't know about type arguments at all, since they are erased at runtime. KType is, but needs the full kotlin reflection library for most functionality.

I know that they are completely different values. I hoped my example would give an idea of what I'm trying to archive. But I guess I'll just provide Foo<Bar>
to the method instead of just Bar

I probably misunderstood what you were trying to do. Why the object mapper read/write?

The server replies with a json structure that is mapped to Map<String, Any?> from the sdk. Then I'm trying to remap it to a more specific (strongly typed properties) dto. But I'm pretty sure I got something wrong in my head. Thanks anyway ;)
