bool	isValidMove (int xSrc, int ySrc, int xDest, int yDest)
	Returns true iff the parameters represent a valid move. More...
bool	move (int xSrc, int ySrc, int xDest, int yDest)
	Moves the piece from (xSrc, ySrc) to (xDest, yDest). If this move takes a king, then it will remove all pieces of the same color as the king that was taken and return true to indicate that the move ended the game. More...
int	moves (int *pOutMoves, int col, int row)
	Pass in the coordinates of a square with a piece on it and it will return the number of moves that piece can make and put the coordinates of the moves in pOutMoves (first col, then row, so pOutMoves should be big enough to hold 2 * MAX_PIECE_MOVES values) More...
Piece	piece (int col, int row, bool *pbWhite)
	Returns the piece located at position (col, row), and sets *pbWhite to true if the piece is white. More...
void	printBoard (std::ostream &stream)
	Print a representation of the board to the specified stream. More...
void	resetBoard ()
	Sets up the board for a new game. More...
void	setPiece (int col, int row, Piece piece, bool white)
	Sets the piece at location (col, row). If piece is None, then it doesn't matter what the value of white is. More...

bool GClasses::GChessBoard::isValidMove	(	int	xSrc,
		int	ySrc,
		int	xDest,
		int	yDest
	)

Returns true iff the parameters represent a valid move.

bool GClasses::GChessBoard::move	(	int	xSrc,
		int	ySrc,
		int	xDest,
		int	yDest
	)

Moves the piece from (xSrc, ySrc) to (xDest, yDest). If this move takes a king, then it will remove all pieces of the same color as the king that was taken and return true to indicate that the move ended the game.

int GClasses::GChessBoard::moves	(	int *	pOutMoves,
		int	col,
		int	row
	)

Pass in the coordinates of a square with a piece on it and it will return the number of moves that piece can make and put the coordinates of the moves in pOutMoves (first col, then row, so pOutMoves should be big enough to hold 2 * MAX_PIECE_MOVES values)

Piece GClasses::GChessBoard::piece ( int  col, int  row, bool *  pbWhite  )

inline

Returns the piece located at position (col, row), and sets *pbWhite to true if the piece is white.

void GClasses::GChessBoard::printBoard

(

std::ostream &

stream

)

Print a representation of the board to the specified stream.

void GClasses::GChessBoard::resetBoard

(

)

Sets up the board for a new game.

void GClasses::GChessBoard::setPiece ( int  col, int  row, Piece  piece, bool  white  )

inline

Sets the piece at location (col, row). If piece is None, then it doesn't matter what the value of white is.
