kotlinlang

Not sure if this is the best channel to ask, but do Kotlin lambdas not exist as a runtime interface? For example, `Class.forName("kotlin.Function0")` fails. And is there a way to have them exist? Maybe some compiler flag? I want to call the invoke function from JNI.

`kotlin.Function` and `kotlin.coroutines.SuspendFunction` are not exists at runtime
On JVM they are mapped to `kotlin.jvm.functions.FunctionN`

I see, thanks. I wasn’t able to make it work for suspend functions, finally I found out it’s mapped to `kotlin.jvm.functions.Function(N+1)` . For the continuation I guess

Btw it would be nice if these things were handled by `org.jetbrains.kotlin.resolve.jvm.JvmClassName`. For lambdas but also more common things like kotlin/String, kotlin/Any (should be java/lang) which are hardly useful

What do you mean?
java.lang mappings exist only during compilation on jvm. In js and native there are actual kotlin. classes

I mean, as a plugin author, I am using `JvmClassName` to get a JVM friendly name, with `/` , `$` and so on. I was saying that it would be nice if `JvmClassName` also did the string conversion between impossible types like kotlin/Any =&gt; java/lang/Object and more delicate ones like suspend functions

Well, `JvmClassName` is an internal utility which does what it does
If you want to map kotlin classes to java runtime you can use `KotlinTypeMapper`/`IrTypeMapper`

You can also use `JavaToKotlinClassMap` just for the class name mapping logic
