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.

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).

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[] limbs, 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.

protected void mult(long[] a, long[] b, long[] r)

Implements abstract sun.security.util.math.intpoly.IntegerPolynomial.mult.

Doc from sun.security.util.math.intpoly.IntegerPolynomial.mult.

Multiply two IntegerPolynomial representations (a and b) and store the result in an IntegerPolynomial representation (r). Requires that a.length == b.length == r.length == numLimbs. It is allowed for a and r to be the same array.
