Constructor from a base 10 represention of a BigInteger.

Parameters:

encoding - a base 10 represention of a BigInteger.

TestRandomBigInteger

public TestRandomBigInteger(java.lang.String encoding,
                            int radix)

Constructor from a base radix represention of a BigInteger.

Parameters:

encoding - a String BigInteger of base radix.

radix - the radix to use.

TestRandomBigInteger

public TestRandomBigInteger(byte[] encoding)

Constructor based on a byte array.

Parameters:

encoding - a 2's complement representation of the BigInteger.

TestRandomBigInteger

public TestRandomBigInteger(int bitLength,
                            byte[] encoding)
