Kotlin - KClass<*> from KType

In Kotlin, I can obtain a `KType` from a `KClass<*>` like so:

Int::class.createType()

> kotlin.Int

How do I do the reverse and obtain the `KClass<Int>` from a `KType` representing a `kotlin.Int`?

You can use [`KType.classifier`](

) for this:

val intType : KType = Int::class.createType()
val intClassifier : KClassifier? = intType.classifier
assertEquals(Int::class, intClassifier) // true

Note that since 1.3.40 you can also (at least on the JVM) use the experimental [`typeOf<Int>()`](

). You may want to have a look at the [1.3.40-announcement](

Speaking of the JVM: on the JVM you can also use [`KType.jvmErasure`](

) to get the actual class as also [marstran](
