Scala Pickling and type parameters

Question

I\'m using Scala Pickling, an automatic serialization framework for Scala. According to the author\'s slides, any type T can be pickled as long as there is an impli

Answer 1

Looking at the project, it seems you need either an scala.pickling.SPickler or a scala.pickling.DPickler (static and dynamic, respectively) in order to pickle a particular type.

The pickle methods are macros. I suspect that if you pickle with an SPickler, the macro will require the compile time type of your class to be known.

Thus, you may need to do something similar to:

object Foo {
  def bar(t: SomeClass1) = t.pickle
  def bar(t: SomeClass2) = t.pickle
  def bar(t: SomeClass3) = t.pickle
  // etc
}

Alternatively, a DPickler may do the trick. I suspect that you'll still have to write some custom pickling logic for your specific types.
