  8. def decompose (a: Any)(implicit formats: Formats): JValue

    Decompose a case class into JSON.

    Example:

    case class Person(name: String, age: Int)
    implicit val formats = org.json4s.DefaultFormats
    Extraction.decompose(Person("joe", 25)) == JObject(JField("age",JInt(25)) :: JField("name",JString("joe")) :: Nil)
    

  9. def decomposeWithBuilder [T] (a: Any, builder: JsonWriter[T])(implicit formats: Formats): T
