Constructor Detail

Polyline2D

public Polyline2D()

Constructor.

Polyline2D

public Polyline2D(float[] xpoints,
                  float[] ypoints,
                  int npoints)

Constructor.

Parameters:

xpoints - an array of x coordinates

ypoints - an array of y coordinates

npoints - the total number of points in the Polyline2D

Throws:

NegativeArraySizeException - if the value of npoints is negative.

IndexOutOfBoundsException - if npoints is greater than the length of xpoints or the length of ypoints.

NullPointerException - if xpoints or ypoints is null.

Polyline2D

public Polyline2D(int[] xpoints,
                  int[] ypoints,

Constructor.

Parameters:

xpoints - an array of x coordinates

ypoints - an array of y coordinates

npoints - the total number of points in the Polyline2D

Throws:

NegativeArraySizeException - if the value of npoints is negative.

IndexOutOfBoundsException - if npoints is greater than the length of xpoints or the length of ypoints.

NullPointerException - if xpoints or ypoints is null.
