location and return a Ref instance that provides access to that location.

Ref.View provides access to the contents of a Ref without requiring
that an implicit InTxn be 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 active View's methods are
still atomic, but only for the duration of the method call.

A mental model of View is that view.foo(args) acts like
atomic { implicit t => view.ref.foo(args) }.

Returns a Ref instance that manages a newly allocated memory location,
initializing it to hold initialValue. The returned Ref is not part
of any transaction's read or write set.

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]]

Returns a Ref instance that manages a newly allocated memory location
holding values of type A. If you have an initial value v0 available,
Ref(v0) should be preferred.
