Concrete methods

def transformPickler[A, B](transformFrom: B => A)(transformTo: A => B)(implicit p: Pickler[B]): Pickler[A]

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.

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((t: Long) => new java.util.Date(t))(_.getTime)

Note that parameters are in reversed order.

Type Params
A

Type of the original object

B

Type for the object used for pickling

Value Params
transformFrom

Function that takes B and transforms it into A

transformTo

Function that takes A and transforms it into B
