Class ConcurrentBox<T>

java.lang.Object
  java.util.concurrent.atomic.AtomicReference<T>
      edu.rice.cs.plt.concurrent.ConcurrentBox<T>

All Implemented Interfaces:

Box<T>, Thunk<T>, java.io.Serializable

public class ConcurrentBox<T>
extends java.util.concurrent.atomic.AtomicReference<T>
implements Box<T>

A thread-safe box implementation. Extends AtomicReference so that it can be treated as a Box.

As a wrapper for arbitrary objects, instances of this class will serialize without error only if the wrapped object is serializable.
