Method Detail

wrapCurve

protected static <T extends ContinuousCurve2D> Collection<T> wrapCurve(T curve)

getAsPolyline

public Polyline2D getAsPolyline(int n)

Description copied from interface: ContinuousCurve2D

Returns an approximation of the curve as a polyline with n line segments. If the curve is closed, the method should return an instance of Ring2D.

Specified by:

getAsPolyline in interface ContinuousCurve2D

Parameters:

n - the number of line segments

Returns:

a polyline with n line segments.

getContinuousCurves

public Collection<? extends ContinuousCurve2D> getContinuousCurves()

Description copied from interface: Curve2D

Returns the collection of continuous curves which constitute this curve.

Specified by:

getContinuousCurves in interface Curve2D

Returns:

a collection of continuous curves.

getFirstPoint

public Point2D getFirstPoint()

Description copied from interface: Curve2D

Get the first point of the curve. It must returns the same result as getPoint(getT0()).

Specified by:

getFirstPoint in interface Curve2D

Returns:

the first point of the curve

getLastPoint

public Point2D getLastPoint()

Description copied from interface: Curve2D

Get the last point of the curve. It must returns the same result as getPoint(getT1()).

Specified by:

getLastPoint in interface Curve2D

Returns:

the last point of the curve.

draw

public void draw(Graphics2D g2)

Description copied from interface: Curve2D

Draws the curve on the given Graphics2D object.

Specified by:

draw in interface Curve2D

Specified by:

draw in interface Shape2D

Parameters:

g2 - the graphics to draw the curve

getAsAWTShape

public Shape getAsAWTShape()

Specified by:

getAsAWTShape in interface Curve2D

Returns:

the shape corresponding to this curve

clone

public abstract ContinuousCurve2D clone()

Description copied from interface: Curve2D

Overrides Object declaration to ensure Curve2D implementation are cloned as Curve2D.

Specified by:

clone in interface Curve2D

Overrides:

clone in class Object

Returns:

the cloned curve
