Class AtomicLongFieldUpdater<T>

java.lang.Object
java.util.concurrent.atomic.AtomicLongFieldUpdater<T>
Type Parameters:
T - The type of the object holding the updatable field

public abstract class AtomicLongFieldUpdater<T> extends Object
A reflection-based utility that enables atomic updates to designated volatile long fields of designated classes. This class is designed for use in atomic data structures in which several fields of the same node are independently subject to atomic updates.

Note that the guarantees of the compareAndSet method in this class are weaker than in other atomic classes. Because this class cannot ensure that all uses of the field are appropriate for purposes of atomic access, it can guarantee atomicity only with respect to other invocations of compareAndSet and set on the same updater.

Object arguments for parameters of type T that are not instances of the class passed to newUpdater(java.lang.Class<U>, java.lang.String) will result in a ClassCastException being thrown.
