Enum Constant Details

MANHATTAN

public static final AStarSearch.SearchType MANHATTAN

The distance it takes when only the four primary directions can be moved in.

CHEBYSHEV

public static final AStarSearch.SearchType CHEBYSHEV

The distance it takes when diagonal movement costs the same as cardinal movement.

EUCLIDEAN

public static final AStarSearch.SearchType EUCLIDEAN

The distance it takes as the crow flies.

DIJKSTRA

public static final AStarSearch.SearchType DIJKSTRA

Method Details

values

public static AStarSearch.SearchType[] values()

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

Returns:

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

valueOf

public static AStarSearch.SearchType 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.
