checkNonNull

public static boolean checkNonNull(java.util.List<Point> points)

Used from assert statements of the form:

 assert Util.checkNonNull(points) : "Null points in " + this;
 

in all the implementations of SmartShape.asPoints().

Parameters:

points - the points

Returns:

false if iterating through the points list and dereferencing the x and y fields would cause a NullPointerException

appendDbPoint

public static void appendSvgPoint(java.lang.StringBuilder sb,
                                  Point p)

appendSvgPoint

public static void appendSvgPoint(java.lang.StringBuilder sb,
                                  double x,
                                  double y)

appendSegment

public static boolean appendSegment(java.lang.StringBuilder sb,
                                    boolean first,
                                    double x,
                                    double y)

pointsToPath

public static java.lang.String pointsToPath(java.util.List<Point> points,
                                            boolean close)

parsePointsToPath

public static java.lang.String parsePointsToPath(java.lang.String str,
                                                 boolean close)

parseAwtPath

public static java.awt.Shape parseAwtPath(java.lang.String str)

parsePoints

public static java.util.List<Point> parsePoints(java.lang.String str)

points

public static java.util.List<Point> points(double x,
                                           double y,
                                           double w,
                                           double h)

Returns the four corner points of a rectangle

Parameters:

x - the top-left corner's x coordinate (the lowest x)

y - the top-left corner's y coordinate (the lowest y)

w - width of the rectangle so that x+w gives the highest x

h - height of the rectange so taht y+h gives the highest y

Returns:

a list of points of the form: (x,y),(x+w,y),(x+w,y+h),(x,y+h)
