Atomic update of AtomicReference

Problem

I like the AtomicReference class. When used with a immutable class, it offers quite a nice and efficient abstraction for concurrent data structure. One thing it is missing, in my opinion, is the atomic update method, ie.

  val list = new AtomicReference(List(1,2,3))
  list.update(list => list.map(_ *2))

Solution

You just need to import the Atomic class, and it will pimp the AtomicReference, so you can call the update method. See below: Enjoy!
