I am currently working on a research project using Akka Clustering. According to the documentation, Jackson is the preferred serializer, and I am particularly interested in the CBOR binary format due to heavy use of doubles in my work. I am, however, using a heavily polymorphic type pulled in from an external library, and the recommended way to allow for a polymorphic type defined in the Akka docs is to use the @JsonSubTypes and @JsonTypeInfo annotations to define the different types.
Due to large number of extended types from this trait, it would be very difficult to comprehensively define every one of them, and would require editing the source code of the library I’m using. Is there any other way to do so? The code is perfectly serialized and deserialized if sent through the standard Java serialization.
This example is similar to my issue, and is taken from the Akka docs. So my question is essentially: Would it be possible to serialize this case class without the ability to directly add annotations to the trait?
final case class Zoo(primaryAttraction: Animal) extends CborSerializable sealed trait Animal final case class Lion(name: String) extends Animal final case class Elephant(name: String, age: Int) extends Animal
