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.

public class AtomicStampedReference<V> {
// Public Constructors
     public AtomicStampedReference(V initialRef, int initialStamp);  
// Public Instance Methods
     public boolean attemptStamp(V expectedReference, int newStamp);  
     public boolean compareAndSet(V expectedReference, V newReference, 
        int expectedStamp, int newStamp);  
     public V get(int[ ] stampHolder);  
     public V getReference( );  
     public int getStamp( );  
     public void set(V newReference, int newStamp);  
     public boolean weakCompareAndSet(V expectedReference, V newReference, 
        int expectedStamp, int newStamp);
