  9. def flat(tagOwrites: OWrites[String]): TypeTagOWrites

    Encodes a tagged type by adding an extra field to the base A JSON representation.

    Encodes a tagged type by adding an extra field to the base A JSON representation.

    For instance, consider the following type definition:

    sealed trait Foo
    case class Bar(s: String, i: Int) extends Foo
    case object Baz extends Foo

    And also:

    implicit val fooOWrites: OWrites[Foo] = derived.flat.owrites((__ \ "type").write)

    The JSON representation of Bar("quux", 42) is then the following JSON object:

    {
      "type": "Bar",
      "s": "quux",
      "i": 42
    }

    An important edge case will happen if a case class we are deriving for has its own Writes that does not produce a JsObject (like Json.valueFormat), in this case we will synthesize a wrapper on-the-fly. See the tests and SyntheticWrapper.

    tagOwrites

    A way to encode the type tag as a JSON object (whose fields will be merged with the base JSON representation)

  14. val nested: TypeTagOWrites

    Encodes a tagged type by creating a JSON object wrapping the actual A JSON representation.

    Encodes a tagged type by creating a JSON object wrapping the actual A JSON representation. This wrapper is an object with just one field whose name is the type tag.

    For instance, consider the following type definition:

    sealed trait Foo
    case class Bar(s: String, i: Int) extends Foo
    case object Baz extends Foo

    The JSON representation of Bar("quux", 42) is the following JSON object:

    {
      "Bar": {
        "s": "quux",
        "i": 42
      }
    }
