Nurbs Curve function set for dependency node data.
MFnNurbsCurveData allows the creation and manipulation of NurbsCurve data objects for use in the dependency graph.
If a user written dependency node either accepts or produces Nurbs Curves, then this class is used to create data blocks into which Nurbs Curves can be constructed before being passed to other dependency graph nodes. The MDataHandle::type method will return kNurbsCurve when data of this type is present.
If a node is receiving a Nurbs Curve via an input attribute, the asNurbsCurve method of MDataHandle can be used to access that input Nurbs Curve.
If a node is to create a Nurbs Curve and send it via an output attribute, a new MFnNurbsCurveData must be instantiated and then the create method called to build the actual data block as an MObject. This MObject should be passed to the MFnNurbsCurve::create method as the parentOrOwner parameter so that the Nurbs Curve will be constructed inside the data block. The MDataHandle::set routine is then used to pass the data block down the connection.
