9. trait DefaultWriters extends AnyRef

   

10. trait DoubleJsonFormats extends DefaultJsonFormats with DefaultReaders with DoubleWriters

    

11. trait DoubleWriters extends DefaultWriters

    

12. class DynamicJValue extends Dynamic

    

13. trait DynamicJValueImplicits extends AnyRef

15. case class FieldSerializer[A](serializer: PartialFunction[(String, Any), Option[(String, Any)]] = Map(), deserializer: PartialFunction[JField, JField] = Map(), includeLazyVal: Boolean = false)(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")
    )
    

    The third optional parameter "includeLazyVal" determines if serializer will serialize/deserialize lazy val fields or not.

16. case class FileInput(file: File) extends JsonInput with Product with Serializable

    

17. trait Formats extends Serializable

    

    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)
