Let say I have a class:

@Serializable
data class SomeClass(val a: Int)

And a function that can receive pretty much everythin:
fun someFunction(object: Any)

How can I check that the function’s parameter is Serializable? I did try something like:

when (object) {
   is Serializable -> doSomething()
}

But that doesn’t work. Someone has some lights to help me?

The @Serializable annotation doesn’t add any marker interfaces to the class. A better bet is probably to pass the serializer to that function directly (which is how the Kotlin libs handle this): fun <T> someFunction(obj: T, serializer: KSerializer<T>)

try this:

import kotlinx.serialization.ImplicitReflectionSerializer
import kotlinx.serialization.serializer

@ImplicitReflectionSerializer
fun isSerializable(obj: Any?): Boolean {
    return try {
        obj!!::class.serializer()
        true
    } catch (e: Exception) {
        false
    }
}

@Robert Jaros Thanks for the answer! It did work 🙂
