Method Detail

values

public static Bitboard.Diagonal[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Bitboard.Diagonal c : Bitboard.Diagonal.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Bitboard.Diagonal valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getBySquareIndex

public static Bitboard.Diagonal getBySquareIndex(int sqrInd)

Returns the diagonal of the chess board on which the input parameter square lies.

Parameters:

sqrInd - The index of a square.

Returns:

The diagonal on which the square the index points to is.
