NoTag

class NoTag extends AnyRef

Specifies that the base codec should not affect the subclasses' JsonCodecs at all and that the decoder should simply try each codec in turn, in the order they were provided to the builder, until it finds one that succeeds.

Attributes
sealed abstract
Example: 

  1. abstract class Base
case class SubclassA(name: String) extends Base
case class SubclassB(x: Int, y: Int) extends Base

implicit val aCodec = SimpleJsonCodecBuilder[SubclassA].build("name", _.name)
implicit val bCodec = SimpleJsonCodecBuilder[SubclassB].build("x", _.x, "y", _.y)

val baseCodec = SimpleHierarchyCodecBuilder[Base](NoTag).
   branch[SubclassA].
   branch[SubclassB].
   build

println(baseCodec.encode(SubclassA("John"))) // { "name" : "John" }
println(baseCodec.encode(SubclassB(1, 2))) // { "x" : 1, "y" : 2 }
