final class TRef[A] extends Serializable

A TRef is a purely functional description of a mutable reference that can be modified as part of a transactional effect. The fundamental operations of a TRef are set and get. set transactionally sets the reference to a new value. get gets the current value of the reference.

NOTE: While TRef provides the transactional equivalent of a mutable reference, the value inside the TRef should be immutable. For performance reasons TRef is implemented in terms of compare and swap operations rather than synchronization. These operations are not safe for mutable values that do not support concurrent access.
