Constructor Detail

Double

public Double(Point2D[] points)

Creates a new IlvPolygon2D.Double instance, connecting given points.

Parameters:

points - A non-empty array of points.

Double

public Double(double[] xpoints,
              double[] ypoints,
              int npoints)

Creates a new IlvPolygon2D.Double instance, connecting given points.

Parameters:

xpoints - An array containing the x values of the points. Its length must be at least npoints.

ypoints - An array containing the y values of the points. Its length must be at least npoints.

npoints - The number of points.

Double

public Double(float[] xpoints,
              float[] ypoints,
              int npoints)

Creates a new IlvPolygon2D.Double instance, connecting given points. The points are given with less precision.

Parameters:

xpoints - An array containing the x values of the points. Its length must be at least npoints.

ypoints - An array containing the y values of the points. Its length must be at least npoints.

npoints - The number of points.

Double

public Double(int[] xpoints,
              int[] ypoints,
              int npoints)

Creates a new IlvPolygon2D.Double instance, connecting given points. The points are given as integers.

Parameters:

xpoints - An array containing the x values of the points. Its length must be at least npoints.

ypoints - An array containing the y values of the points. Its length must be at least npoints.

npoints - The number of points.
