Method Summary

Modifier and Type	Method and Description
private void	carryReduce(long[] c, long[] r)
protected void	finalCarryReduceLast(long[] limbs) Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.finalCarryReduceLast. Carry out of the last limb and reduce back in. This method will be called as part of the "finalReduce" operation that puts the representation into a fully-reduced form.
public IntegerPolynomial.ImmutableElement	getElement(byte[] v, int offset, int length, byte highByte) Overrides sun.security.util.math.intpoly.IntegerPolynomial.getElement. Implements sun.security.util.math.IntegerFieldModuloP.getElement. Allow more general (and slower) input conversion that takes a large value and reduces it.
private void	modReduceInBits(long[] limbs, int index, int bits, long x)
protected void	mult(long[] a, long[] b, long[] r) Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.mult. Multiply two IntegerPolynomial representations (a and b) and store the result in an IntegerPolynomial representation (r).
private void	multOnly(long[] a, long[] b, long[] c) Multiply a and b, and store the result in c.
protected void	reduce(long[] a) Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.reduce. Reduce an IntegerPolynomial representation (a) and store the result in a.
protected void	reduceIn(long[] c, long v, int i) Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.reduceIn.
protected void	square(long[] a, long[] r) Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.square. Multiply an IntegerPolynomial representation (a) with itself and store the result in an IntegerPolynomialRepresentation (r).

protected void finalCarryReduceLast(long[] limbs) Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.finalCarryReduceLast. Doc from sun.security.util.math.intpoly.IntegerPolynomial.finalCarryReduceLast. Carry out of the last limb and reduce back in. This method will be called as part of the "finalReduce" operation that puts the representation into a fully-reduced form. It is representation- specific, because representations have different amounts of empty space in the high-order limb. Requires that limbs.length=numLimbs. Annotations @Override
