buildDecodingArray

private static byte[] buildDecodingArray()

longFromByteArray

static long longFromByteArray(byte[] bytes,
                              int offset)

Returns the long value whose big-endian representation is stored in the first 8 bytes of bytes starting from the offset.

Parameters:

bytes - the byte array representation of the long.

offset - the starting offset in the byte array.

Returns:

the long value whose big-endian representation is given.

Throws:

java.lang.IllegalArgumentException - if bytes has fewer than 8 elements.

longToByteArray

static void longToByteArray(long value,
                            byte[] dest,
                            int destOffset)

Stores the big-endian representation of value in the dest starting from the destOffset.

Parameters:

value - the value to be converted.

dest - the destination byte array.

destOffset - the starting offset in the destination byte array.

longFromBase16String

static long longFromBase16String(java.lang.CharSequence chars,
                                 int offset)

Returns the long value whose base16 representation is stored in the first 16 chars of chars starting from the offset.

Parameters:

chars - the base16 representation of the long.

offset - the starting offset in the CharSequence.

longToBase16String

static void longToBase16String(long value,
                               char[] dest,
                               int destOffset)

Appends the base16 encoding of the specified value to the dest.

Parameters:

value - the value to be converted.

dest - the destination char array.

destOffset - the starting offset in the destination char array.

byteToBase16String

static void byteToBase16String(byte value,
                               char[] dest,
                               int destOffset)

Encodes the specified byte, and returns the encoded String.

Parameters:

value - the value to be converted.

dest - the destination char array.

destOffset - the starting offset in the destination char array.

byteFromBase16String

static byte byteFromBase16String(java.lang.CharSequence chars,
                                 int offset)

Decodes the specified two character sequence, and returns the resulting byte.

Parameters:

chars - the character sequence to be decoded.

offset - the starting offset in the CharSequence.

Returns:

the resulting byte

Throws:

java.lang.IllegalArgumentException - if the input is not a valid encoded string according to this encoding.

decodeByte
