object Ref contains factory methods that allocate an STM-managed memory
location and return a Ref instance that provides access to that location.

Ref.Viewprovides access to the contents of aRefwithout requiring that an implicitInTxnbe available.Ref.Viewprovides access to the contents of aRefwithout requiring that an implicitInTxnbe available. When called from within the dynamic scope of a transaction,View's methods operate as part of that transaction. When there is no transaction activeView's methods are still atomic, but only for the duration of the method call.A mental model of
Viewis thatview.foo(args)acts likeatomic { implicit t => view.ref.foo(args) }.

Refinstance that manages a newly allocated memory location, initializing it to holdinitialValue. The returnedRefis not part of any transaction's read or write set.Example:
val x = Ref("initial") // creates a Ref[String] val list1 = Ref(Nil : List[String]) // creates a Ref[List[String]] val list2 = Ref[List[String]](Nil) // creates a Ref[List[String]]
