Class Description


~TVirtualFitter()
*-*-*-*-*-*-*-*-*-*-*default destructor*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ==================

TVirtualFitter* Fitter(TObject *obj, Int_t maxpar)
 Static function returning a pointer to the current fitter.
 If the fitter does not exist, the default TFitter is created

void SetFitter(TVirtualFitter *fitter, Int_t maxpar)
 Static function to set an alternative fitter

Int_t GetMaxIterations()
 Return the maximum number of iterations

Double_t GetPrecision()
 Return the fit relative precision

void SetMaxIterations(Int_t niter)
 Set the maximum number of iterations

void SetPrecision(Double_t prec)
 Set the fit relative precision
