Remarks
A reflection-based utility that enables atomic updates to designated volatile int
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
will result in a ClassCastException
being thrown.
