Method Detail

values

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

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

valueOf

public static TranslationDirection valueOf(java.lang.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:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
java.lang.NullPointerException - if the argument is null

getDirection

public static TranslationDirection getDirection(java.awt.Point startPoint,
                                                java.awt.Point endPoint)
Returns the direction from the provided start point to the end point. Returns null, if both points are at the same location.


getDirection

public static TranslationDirection getDirection(java.awt.geom.Point2D.Double startPoint,
                                                java.awt.geom.Point2D.Double endPoint)
Returns the direction from the provided start point to the end point. Returns null, if both points are at the same location.
