AtomicStampedReference<V>java.util.concurrent.atomic

Java 5.0

This threadsafe class holds a mutable reference to an object of type V and also holds a mutable int value or "stamp." It defines atomic operations and volatile access semantics for the reference and the stamp. This class works just like AtomicMarkableReference except that an int "stamp" replaces the boolean "mark." See AtomicMarkableReference for further details.
