Adaptor2d_Curve2d Class Reference

Root class for 2D curves 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 concrete class is provided:
Geom2dAdaptor_Curve for a curve from the Geom2d package.
