Method Detail

encode

private byte[] encode(StartPawnSeries pawns,
                      int outputLength)

Encode the pawns given, with a fixed length of output. It is assumed that there are no repetitions in the list.

Parameters:

pawns -

outputLength -

Returns:

the encoded bytes.

encode

public byte[] encode(StartPawnSeries pawns,
                     boolean padding)

Encode the pawns given as a byte array. Pad to 8 bytes if 'padding' is true. It is assumed that there are no repetitions in the list.

Parameters:

pawns -

padding -

Returns:

the encoded byte array.

encode

public byte[] encode(StartPawnSeries pawns)

Encode the pawns given as a byte array. It is assumed that there are no repetitions in the list.

Parameters:

pawns -

Returns:

the encoded byte array.

setBytes

public void setBytes(byte[] bytes)

Set up a byte array that can then be decoded, by calling decode() iteratively.

Parameters:

bytes -

decode().

decode

public StartPawn decode()

Decode the next value from the byte array set up previously with setBytes(byte[]).

Returns:

the next pawn value, or null if there are no more values.
