Method Summary

abstract SmoothCurve2D	clone() Overrides Object declaration to ensure Curve2D implementation are cloned as Curve2D.
Vector2D	getLeftTangent(double t)
Vector2D	getRightTangent(double t)
Collection<Point2D>	getSingularPoints() Returns an empty set of Point2D, as a smooth curve does not have singular points by definition.
Collection<? extends SmoothCurve2D>	getSmoothPieces() Returns a set of smooth curves.
boolean	isSingular(double pos) Returns always false, as a smooth curve does not have singular points by definition.
