Estimate of max legal moves per position: max ever actually recorded in a random game is 71.

allMoves

final Moves allMoves

Store all the legal next moves from this board position.

movesEnumerated

protected boolean movesEnumerated

Have we enumerated the next moves for this position yet?

movesCompleted

protected boolean movesCompleted

Have we enumerated ALL the next moves for this position yet?

moveEnumeration

private java.util.Enumeration moveEnumeration

Constructor Detail

GameMoves

public GameMoves()

Method Detail

getMoveCount

public short getMoveCount()

Count all the the possible legal moves -- don't call this if you want to avoid enumerating all possible legal moves for efficiency reasons, go right to getMove().

Returns:

count of the number of legal next Moves for this Game.

getMove

public Move getMove(short move)

Parameters:

move - the index of the legal move we're locating.

Returns:

the legal move at this location -- only computes legal moves up to this point for efficiency.

getMoveEnumeration

protected java.util.Enumeration getMoveEnumeration()

Retrieves or creates an enumeration of all the legal moves.

Returns:

an Enumeration of all the legal moves.

computeMoves

protected void computeMoves(short moveNeeded)

Computes all next legal moves up to a certain move index.

Parameters:

moveNeeded - the index of the last legal move we need (or Short.MAX_SHORT for all!)

computeMoves

protected void computeMoves()

Compute all the legal moves.

applyMove

public byte applyMove(Move move)

Apply a specific move to this Game. Apply the move to the parent class -- but then invalidate the stored list of legal moves.

Overrides:

applyMove in class Game

Returns:

the index of the captured piece, if any (special case for ep).
