public AbstractContinuousCurve2D()

Method Detail

asPolyline

public LinearCurve2D asPolyline(int n)

Converts this continuous curve to an instance of LinearCurve2D with the given number of edges. Returns either an instance of Polyline2D or LinearRing2D, depending on the curve is closed or not. This method can be overridden to return the correct type.

Specified by:

asPolyline in interface ContinuousCurve2D

Parameters:

n - the number of line segments

Returns:

a polyline with n line segments.

ContinuousCurve2D.asPolyline(int)

continuousCurves

public java.util.Collection<? extends ContinuousCurve2D> continuousCurves()

Description copied from interface: Curve2D

Returns the collection of continuous curves which constitute this curve.

Specified by:

continuousCurves in interface Curve2D

Returns:

a collection of continuous curves.

firstPoint

public Point2D firstPoint()

Description copied from interface: Curve2D

Returns the first point of the curve. It must returns the same result as point(t0()).

Specified by:

firstPoint in interface Curve2D

Returns:

the first point of the curve

lastPoint

public Point2D lastPoint()

Description copied from interface: Curve2D

Returns the last point of the curve. It must returns the same result as this.point(this.t1()).

Specified by:

lastPoint in interface Curve2D

Returns:

the last point of the curve.

Specified by:

draw in interface Shape2D

Parameters:

g2 - the graphics to draw the curve in

asAwtShape

public java.awt.Shape asAwtShape()

Specified by:

asAwtShape in interface Curve2D

Returns:

the shape corresponding to this curve
