Examples of java.util.concurrent.atomic.AtomicReferenceArray

java.util.concurrent.atomic.AtomicReferenceArray
An array of object references in which elements may be updated atomically. See the {@link java.util.concurrent.atomic} packagespecification for description of the properties of atomic variables. @since 1.5 @author Doug Lea @param < E> The base class of elements held in this array
