| virtual Standard_Integer | GetStateNumber () |
| Returns the state of the function corresponding to the latestcall of any methods associated with the function. This function is called by each of the algorithms described later which define the function Integer Algorithm::StateNumber(). The algorithm has the responsibility to call this function when it has found a solution (i.e. a root or a minimum) and has to maintain the association between the solution found and this StateNumber. Byu default, this method returns 0 (which means for the algorithm: no state has been saved). It is the responsibility of the programmer to decide if he needs to save the current state of the function and to return an Integer that allows retrieval of the state. | |

Detailed Description
Deferred class for a function used to compute a blending surface between a surface and a curve, using a guide line. This function is used to find a solution on a done restriction of the surface.
The vector <X> used in Value, Values and Derivatives methods has to be the vector of the parametric coordinates wguide, wcurv, wrst where wguide is the parameter on the guide line, wcurv is the parameter on the curve, wrst is the parameter on the restriction on the surface.
