# serialization

Hi, I am still struggling with tree-like serializers. I have following serializeable node:

data class NodeItem<M : Meta>(val node: M) : MetaItem<M>() {
        override fun toString(): String = node.toString()

        @Serializer(NodeItem::class)
        companion object : KSerializer<NodeItem<out Meta>> {
            ...
        }
    }

M is the recursive generics type. It is actually ignored in the serializer since we always use top type.

When I use it, I get class hep.dataforge.meta.MetaBuilder is not registered for polymorphic serialization in the scope of class hep.dataforge.meta.Meta . Is it possible to somehow bypass polymorphic serializers and actually use interface type for serialization?

I solved the problem with writing

@Serializable(MetaSerializer::class) val node: M

. I guess it could cause classcast errors, but will hold for now.
