copy()

virtual Geometry* Geom::GeomBSplineCurve::copy ( void  ) const

virtual

returns a copy of this object having a new randomly generated tag. If you also want to copy the tag, you may use clone() instead. For creation of geometry with other handles, with or without the same tag, you may use the constructors and the sethandle functions. The tag of a geometry can be copied to another geometry using the assignTag function.

Implements Geom::Geometry.
