final case class Discriminated[X, D](codec: Codec[D], framing: CodecTransformation) extends Product with Serializable

Wrapper class that indicates subtypes of X are discriminated by type D using the supplied Codec[D].

For example, an implicit Discriminated value can be defined in the companion of a sealed trait, along with implicit Discriminator values in each subtype companion. Given such implicits, a codec for the trait can be automatically derived using Codec[X].

Contains an optional codec transformation, which is applied to every component codec before encoding/decoding. This allows common structure, e.g., size based framing, to be specified in one location.

For example, if each discriminated subtype is prefixed by a size field, the framing could be specified as:

Discriminated[X, D](uint, new CodecTransformation {
  def apply[Z](c: Codec[Z]) = variableSizeBytes(uint16, c)
})
X

type that can be discriminated by discriminator values of type D

D

value type that discriminates Y in context of X from other types using discriminators of D for some type Y
