virtual Standard_Integer GetStateNumber ()
returns the state of the function corresponding to the latest call of any methods associated with the function. This function is called by each of the algorithms described later which defined 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. More...

## Detailed Description

This abstract class describes a Function of 1 Variable used to find a line tangent to a curve and a circle.

## ◆ Geom2dGcc_FunctionTanCirCu()

 Geom2dGcc_FunctionTanCirCu::Geom2dGcc_FunctionTanCirCu ( const gp_Circ2d & Circ, const Geom2dAdaptor_Curve & Curv )

## ◆ Derivative()

 Standard_Boolean Geom2dGcc_FunctionTanCirCu::Derivative ( const Standard_Real X, Standard_Real & Deriv )
virtual
