Detailed Description

Generic board memeber piece API.

This class should be inherited and used as a way to describe chess piece in every board derived from Board class.

Member Enumeration Documentation

Color

enum tt::Piece::Color

strong

Piece color.

setColor(), color()

Constructor & Destructor Documentation

Piece()

tt::Piece::Piece	(	const Position &	pos = {1,1},
		Color	col = Color::White
	)

Construct new Piece.

Parameters

pos	Piece Position
col	Piece Color

color(), position()

Member Function Documentation

board() [1/2]

Board* tt::Piece::board ( )

inline

Piece board.

Returns

Board to which current Piece belongs

board() [2/2]

const Board* tt::Piece::board ( ) const

inline

Piece board.

Returns

Board to which current Piece belongs

color()

Color tt::Piece::color ( ) const

inline

Piece color.

Returns

current Piece color value

diagonalMoves()

Piece::TurnMap tt::Piece::diagonalMoves ( const Piece *  p )

static

Construct diagonal moves TurnMap.

Constructs new TurnMap object where the TurnMap::piece() is set to p. It is defined that piece that performs moves can not step on or over other Piece objects at the Board.

Returns

TurnMap object with p as turn piece

move()

Position tt::Piece::move ( const Position &  to )

virtual

Move piece.

Changes the position() value, uses board() interface to move piece to new location at the underlying Board.

Parameters

to	new Position value

Returns

old Position vlaue

moveMap()

virtual TurnMap tt::Piece::moveMap ( int  mode = 0 ) const

pure virtual

Generic moves.

Note

Developer had and intention that You will define unscoped enumeration for mode in Your Board class. It's value will be passe to function and influence it's behaivor in some way.

Parameters

mode	optional mode constant to influence the moveMap() behaivor in child classes.

Returns

TurnMap object filled with Turn objects. May not contain turns that are not possible because of piece placement

Implemented in tt::chess::King, tt::chess::Queen, tt::chess::Rook, tt::chess::Bishop, tt::chess::Knight, and tt::chess::Pawn.

movesMade()

std::size_t tt::Piece::movesMade ( ) const

inline

static

Construct straight moves (up, down, left, right) TurnMap.

Constructs new TurnMap object where the TurnMap::piece() is set to p. It is defined that piece that performs moves can not step on or over other Piece objects at the Board.

Returns

TurnMap object with p as turn piece

turnIndex()

std::size_t tt::Piece::turnIndex ( ) const

inline
