Enum Constant Detail

EUCLIDEAN

public static final Distance EUCLIDEAN

EUCLIDEAN_SQUARED

public static final Distance EUCLIDEAN_SQUARED

MANHATTAN

public static final Distance MANHATTAN

CHEBYSHEV

public static final Distance CHEBYSHEV

PATHING

public static final Distance PATHING

This implementation may return Double.MAX_VALUE if the positions are on varying levels, or Integer.MAX_VALUE if pathfinding failed.

Method Detail

values

public static Distance[] 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 (Distance c : Distance.values())
    System.out.println(c);

Returns:

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

valueOf

public static Distance 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

getDefaultEvaluator

public static DistanceEvaluator getDefaultEvaluator()

between

public static double between(SceneNode from,
                             SceneNode to)

evaluate

public static double evaluate(DistanceEvaluator algo,
                              SceneNode from,
                              SceneNode to)

evaluate

public abstract double evaluate(int x1,
                                int y1,
                                int level1,
                                int x2,
                                int y2,
                                int level2)
