class HContour: public TNamed

_HADES_CLASS_DESCRIPTION

 This class stores the contour (x,y coordinates of a given number
 of points) and evaluates if a given point (input information) stays
 inside or outside the contour.

 The algorithm used to evaluate if the given point is inside or outside
 the contour was proposed by
 P.Finocchiaro (INFN-LNS,Catania, "finocchiaro@lns.infn.it")

Function documentation

Bool_t addPoint(Float_t x, Float_t y)
 This function adds a new point to the contour.
void deleteLastPoint()
 This function deletes the last defined point in the contour.
void setLink(Bool_t a = kTRUE)
 This function sets the flag which tells if the first and last points
 of the contour are linked or not.
void fillHelperArrays()
 This is a helper function which calculates the equations of all straight
 line pieces of the contour and stores them in arrays slope and offset.
Bool_t checkSelfCross()
 This function makes self cross check of the contour.
Bool_t fillCrossArray(Float_t x, Float_t y)
 This is a helper function which calculates y coordinates of cross points
 of the contour pieces with the perpendicular to the x axis drawn through
 the point (x,y).
void sorting()
 This function makes sorting of the array cross by means of "insert method".
 See Herbert Schildt "Expert C++".
Bool_t isInside(Float_t x, Float_t y)
 This function evaluates if the point (x,y) is inside the contour.
void Paint(Option_t* t)
 This function paints the contour in the current active pad.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 This function executes mouse event in the current active pad.
void show(const Char_t* msg)
 This function prints the message msg.
 Was used at the prototyping stage.
void undo()
 This function makes one step back during the contour definition.
void setAll()
 This function connects the last point of the contour with the first one.
void copy(TObject* hc)
 This function copies contour to hc.
Bool_t checkLimits(Float_t xmin, Float_t xmax, Float_t ymin, Float_t ymax)
 This function checks if the contour is inside the area given by
 xmin, ymin, xmax, ymax. This function is called from Paint(Option_t *)
HContour()
virtual ~HContour()
Int_t DistancetoPrimitive(Int_t px, Int_t py)
{return 0;}
Bool_t isLinked()
{ return kLink; }
void define(Bool_t a = kTRUE)



{ kDefine = a; }
