TransformPickler

case class TransformPickler[A <: AnyRef, B](transformTo: (A) ⇒ B, transformFrom: (B) ⇒ A)(implicit p: Pickler[B], up: Unpickler[B]) extends Product with Serializable

Create a transforming pickler that takes an object of type A and transforms it into B, which is then pickled. Similarly a B is unpickled and then transformed back into A.

This allows for easy creation of picklers for (relatively) simple classes. For example

// transform Date into Long and back
implicit val datePickler = TransformPickler[java.util.Date, Long](
  _.getTime,
  t => new java.util.Date(t))
A

Type of the original object

B

Type for the object used in pickling

transformTo

Function that takes A and transforms it into B

transformFrom

Function that takes B and transforms it into A
