Adaptor2d_HCurve2d Class Reference

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.
