    • Method Detail

      • nextLatitude

        public static double nextLatitude()
        returns next pseudorandom latitude (anywhere)
      • nextLongitude

        public static double nextLongitude()
        returns next pseudorandom longitude (anywhere)
      • nextPointNear

        public static double[] nextPointNear​(Rectangle rectangle)
        Returns next point (lat/lon) for testing near a Box. It may cross the dateline
      • nextPointNear

        public static double[] nextPointNear​(Polygon polygon)
        Returns next point (lat/lon) for testing near a Polygon
      • nextBoxNear

        public static Rectangle nextBoxNear​(Polygon polygon)
        Returns next box for testing near a Polygon
      • nextBox

        public static Rectangle nextBox()
        returns next pseudorandom box: can cross the 180th meridian
      • nextBoxNotCrossingDateline

        public static Rectangle nextBoxNotCrossingDateline()
        returns next pseudorandom box: does not cross the 180th meridian
      • createRegularPolygon

        public static Polygon createRegularPolygon​(double centerLat,
                                                   double centerLon,
                                                   double radiusMeters,
                                                   int gons)
        Makes an n-gon, centered at the provided lat/lon, and each vertex approximately distanceMeters away from the center.

        Do not invoke me across the dateline or a pole!!

      • nextPoint

        public static Point nextPoint()
      • nextLine

        public static Line nextLine()
      • nextCircle

        public static Circle nextCircle()
      • nextPolygon

        public static Polygon nextPolygon()
        returns next pseudorandom polygon
      • toSVG

        public static String toSVG​(Object... objects)
        Returns svg of polygon for debugging.

        You can pass any number of objects: Polygon: polygon with optional holes Polygon[]: arrays of polygons for convenience Rectangle: for a box double[2]: as latitude,longitude for a point

        At least one object must be a polygon. The viewBox is formed around all polygons found in the arguments.

      • containsSlowly

        public static boolean containsSlowly​(Polygon polygon,
                                             double latitude,
                                             double longitude)
        Simple slow point in polygon check (for testing)
