Root class for 2D curves manipulated by handles, on which geometric algorithms work. An adapted curve is an interface between the services provided by a curve, and those required of the curve by algorithms, which use it. A derived specific class is provided: Geom2dAdaptor_HCurve for a curve from the Geom2d package. More...
