#serialization

Got compiler error when tried to compile:

@Serializable
interface EventData

error:

e: java.lang.IllegalStateException: Backend Internal error: Exception during code generation
Cause: Back-end (JVM) Internal error: @Serializable annotation on class EventData would be ignored because it is impossible to serialize it automatically. Provide serializer manually via e.g. companion object

This interface will be used as a marker interface and it will be used on data class X(...) : EventData

what stops you from making it non-serializable?

don't know, from experience serializer is complaining when superclasses was not marked as @Serializable

or it's only for classes?

ok, Thanks! worked

it's for classes which do not have no-arg constructor
