15.  case class FieldSerializer [A](serializer: PartialFunction[(String, Any), Option[(String, Any)]] = Map(), deserializer: PartialFunction[JField, JField] = Map())(implicit mf: Manifest[A]) extends Product with Serializable

    Serializer which serializes all fields of a class too.

    Serializer which serializes all fields of a class too.

    Serialization can be intercepted by giving two optional PartialFunctions as constructor parameters:

    FieldSerializer[WildDog](
      renameTo("name", "animalname") orElse ignore("owner"),
      renameFrom("animalname", "name")
    )
    

16.  case class FileInput (file: File) extends JsonInput with Product with Serializable
17.  trait Formats extends AnyRef

    Formats to use when converting JSON.

    Formats to use when converting JSON. Formats are usually configured by using an implicit parameter:

    implicit val formats = org.json4s.DefaultFormats

    Type hints can be used to alter the default conversion rules when converting Scala instances into JSON and vice versa.

    Type hints can be used to alter the default conversion rules when converting Scala instances into JSON and vice versa. Type hints must be used when converting class which is not supported by default (for instance when class is not a case class).

    Example:

    class DateTime(val time: Long)
    
    val hints = new ShortTypeHints(classOf[DateTime] :: Nil) {
      override def serialize: PartialFunction[Any, JObject] = {
        case t: DateTime => JObject(JField("t", JInt(t.time)) :: Nil)
      }
    
      override def deserialize: PartialFunction[(String, JObject), Any] = {
        case ("DateTime", JObject(JField("t", JInt(t)) :: Nil)) => new DateTime(t.longValue)
      }
    }
    implicit val formats = DefaultFormats.withHints(hints)
