Method Detail

GetUInt64

public static long GetUInt64(byte[] b,
                             int i)

Creates a long from 8 bytes. Because Java does not provide unsigned data types this is a bit tricky. The function takes care to process the sign bit correctly. The created long is in little endian order.

Parameters:

b - The array that contains the bytes to combine.

i - The offset into the byte array where the data starts.

PutBytes

public static void PutBytes(long[] input,
                            byte[] output,
                            int offset,
                            int byteCount)

Disassmble an array of Long into a byte array.

Parameters:

input - The long input array.

output - The byte output array.

offset - The offset into the output array.

byteCount - The number of bytes to disassemble.
