1.  trait BigDecimalJsonFormats extends DefaultJsonFormats with DefaultReaders with BigDecimalWriters
2.  trait BigDecimalWriters extends DefaultWriters
3.  class CustomKeySerializer[A] extends KeySerializer[A]
4.  class CustomSerializer[A] extends Serializer[A]
5.  trait DateFormat extends AnyRef

   Conversions between String and Date.

6.  trait DefaultFormats extends Formats
7.  trait DefaultJsonFormats extends AnyRef
8.  trait DefaultReaders extends DefaultReaders0
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
14.  class ExtractableJsonAstNode 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

36.  case class MappedTypeHints(hintMap: Map[Class[_], String], typeHintFieldName: String = "jsonClass") extends TypeHints with Product with Serializable

    Use a map of keys as type hints.

    Use a map of keys as type hints. Values may not be mapped by multiple keys

37.  case class MappingException(msg: String, cause: Exception) extends Exception with Product with Serializable

49.  trait TypeHints extends AnyRef

    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)
