Method Detail

values

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

Returns:

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

valueOf

public static BentStyle 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

getPath

public java.util.ArrayList<java.awt.geom.Point2D> getPath(java.awt.geom.Rectangle2D start,
                                                          java.awt.geom.Rectangle2D end)

Gets the points at which a line joining two rectangles is bent according to this bent style.

Parameters:

start - the starting rectangle

end - the ending rectangle

Returns:

an array list of points at which to bend the segmented line joining the two rectangles

connectionPoints

private static java.awt.geom.Point2D[] connectionPoints(java.awt.geom.Rectangle2D r)

Gets the four connecting points at which a bent line connects to a rectangle.

getPath

private static java.util.ArrayList<java.awt.geom.Point2D> getPath(BentStyle bent,
                                                                  java.awt.geom.Rectangle2D s,
                                                                  java.awt.geom.Rectangle2D e)

Gets the points at which a line joining two rectangles is bent according to a bent style.

Returns:

an array list of points at which to bend the segmented line joining the two rectangles
