Class Description

                                                                      
 TSpline                                                              
                                                                      
 Base class for spline implementation containing the Draw/Paint       
 methods
void Draw(Option_t *option) 
*-*-*-*-*-*-*-*-*-*Draw this function with its current attributes*-*-*-*-*
*-*                  ==============================================
*-*
*-* Possible option values are:
*-*   "SAME"  superimpose on top of existing picture
*-*   "L"     connect all computed points with a straight line
*-*   "C"     connect all computed points with a smooth curve.
*-*   "P"     add a polymarker at each knot
*-*
*-* Note that the default value is "L". Therefore to draw on top
*-* of an existing picture, specify option "LSAME"
*-*
*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
void Paint(Option_t *option) 
*-*-*-*-*-*-*-*-*-*Paint this function with its current attributes*-*-*-*-*
*-*                ===============================================
void Streamer(TBuffer &R__b) 
 Stream an object of class TSpline.
