Method Summary

static int	writeWholeNum(DataOutput self, BigInteger wholeNum) Enabled: Encodes a whole number (a non-negative integer) using the Waterken Doc ExtensionNumber format.
private static int	writeWholeNum(DataOutput self, BigInteger wholeNum, int highbit) Because this needs to write in big-endian order, but the natural algorithm generates in little endian order, this uses recursion to do the reversal.

Method Detail

writeWholeNum

public static int writeWholeNum(DataOutput self,
                                BigInteger wholeNum)
                         throws IOException

Enabled: Encodes a whole number (a non-negative integer) using the Waterken Doc ExtensionNumber format.

Parameters:

self -

wholeNum -

IOException

writeWholeNum

private static int writeWholeNum(DataOutput self,
                                 BigInteger wholeNum,
                                 int highbit)
                          throws IOException

Because this needs to write in big-endian order, but the natural algorithm generates in little endian order, this uses recursion to do the reversal.

Parameters:

self -

wholeNum -

highbit - Either 0x00 or 0x80, which is or-ed into the low order byte.

Returns:

Throws:

IOException
