43 * Class WorkerForLoop is the abstract base class for a worker for loop that is
44 * executed inside a {@linkplain WorkerRegion}. There are four variations of a
45 * worker for loop, depending on the loop index data type and on whether the
46 * loop stride is implicit or explicit. There is a subclass for each variation;
47 * see the subclasses for further information. The subclasses are:
48 * <UL>
49 *
50 * <LI>
51 * Class {@linkplain WorkerIntegerForLoop} -- loop index is type <code>int</code>,
52 * loop stride is implicit (+1).
53 *
54 * <LI>
55 * Class {@linkplain WorkerIntegerStrideForLoop} -- loop index is type
56 * <code>int</code>, loop stride is explicitly specified.
57 *
58 * <LI>
59 * Class {@linkplain WorkerLongForLoop} -- loop index is type <code>long</code>,
60 * loop stride is implicit (+1).
61 *
62 * <LI>
63 * Class {@linkplain WorkerLongStrideForLoop} -- loop index is type
64 * <code>long</code>, loop stride is explicitly specified.
65 * </UL>
