public abstract class ByteOp
extends Op

Class ByteOp is the abstract base class for a binary operation on byte values, used to do reduction in a parallel program.

Field Summary

static ByteOp	AND The byte bitwise "and" binary operation.
static ByteOp	MAXIMUM The byte maximum binary operation.
static ByteOp	MINIMUM The byte minimum binary operation.
static ByteOp	OR The byte bitwise "or" binary operation.
static ByteOp	PRODUCT The byte product binary operation.
static ByteOp	SUM The byte sum binary operation.
static ByteOp	XOR The byte bitwise "exclusive or" binary operation.

Constructor Summary
