I have some working jackson scala module code for roundtripping scala case classes. Jackson worked great for flat case classes but when I made one which contains a list of other case classes the amount of code I seemed to need was a lot. Consider: abstract class Message case class CardDrawn(player: Long, card: Int, mType: String = "CardDrawn") extends Message case class CardSet(cards: List[CardDrawn], mType: String = "CardSet") extends Message To get the CardSet to roundtrip to/from json with jackson scala module I used a custom serializer/deserializer written in java: object

I need to be able to process large JSON files, instantiating objects from deserializable sub-strings as we are iterating-over/streaming-in the file. For example: Let's say I can only deserialize into instances of the following: case class Data(val a: Int, val b: Int, val c: Int) and the expected JSON format is: { "foo": [ {"a": 0, "b": 0, "c": 0 }, {"a": 0, "b": 0, "c": 1 } ], "bar": [ {"a": 1, "b": 0, "c": 0 }, {"a": 1, "b": 0, "c": 1 } ], .... MANY ITEMS .... , "qux": [ {"a": 0, "b": 0, "c": 0 } } What I would like to do is: import com.codahale.jerkson.Json val dataSeq : Seq[Data] = Json
