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.
