I got a

param.type === nz.salect.objJSON.JVMBranchTest.MenuObject?

where

param:KParameter

. But when I tried to get the class definition from

param.type

via

param.type::class

. Instead of getting the above

MenuObject

, I get a

class kotlin.reflect.jvm.internal.KTypeImpl

. How to get my own class , I mean, a

KClass

? Thanks 🙂

Depending on your use case,

param.type.jvmErasure

might be more helpful

@udalov What’s the differences between the

jvmErasure

and

classifier

?

jvmErasure

returns the class that represents the erasure of the given type on JVM. For normal classes, this is always simply that class. For generic type parameters, this is the erasure of the generic bound, or

Any

if there's no bound. For example, erasure of a simple type like

String

is class

String

itself. Erasure of a type

List<String>

is class

List

. Erasure of

T

in

fun <T> foo() {}

is class

Any

. Erasure of

Y

in

fun <X : Set<String>, Y : X> bar() {}

is class

Set

.
