compress()

static void hoover_chess_utils::pgn_reader::PositionCompressor_FixedLength::compress ( const ChessBoard &  board, CompressedPosition_FixedLength &  out_compressedPosition  )

static

Compresses a chess position with at most 32 pieces.

Parameters

[in]	board	Position
[out]	out_compressedPosition	Compressed position

Exceptions

std::out_of_range

The position has more than 32 pieces.

See CompressedPosition_FixedLength for the specication of position encoding.

decompress()

static void hoover_chess_utils::pgn_reader::PositionCompressor_FixedLength::decompress ( const CompressedPosition_FixedLength &  compressedPosition, std::uint8_t  halfMoveClock, std::uint32_t  moveNum, pgn_reader::ChessBoard &  out_board  )

static

Compresses a chess position with at most 32 pieces.

Parameters

[in]	compressedPosition	Compressed position
[in]	halfMoveClock	Half-move clock
[in]	moveNum	Move number
[out]	out_board	ChessBoard to be set with position represented by compressedPosition

Exceptions

std::out_of_range	Bad compressed format
PgnError	Illegal position
