abstract class Synchronized[A] extends Ref[A]

A Ref.Synchronized is a purely functional description of a mutable reference. The fundamental operations of a Ref.Synchronized are set and get. set sets the reference to a new value. get gets the current value of the reference.

Unlike an ordinary Ref, a Ref.Synchronized allows performing effects within update operations, at some cost to performance. Writes will semantically block other writers, while multiple readers can read simultaneously.
