open override fun <Base : Any> polymorphicDefaultDeserializer(baseClass: KClass<Base>, defaultDeserializerProvider: (className: String?) -> DeserializationStrategy<out Base>?)

Adds a default deserializers provider associated with the given baseClass to the resulting module. defaultDeserializerProvider is invoked when no polymorphic serializers associated with the className were found. className could be null for formats that support nullable class discriminators (currently only Json with useArrayPolymorphism set to false).

This will not affect serialization.
