Class Description

~TVirtualFitter() 
 Cleanup virtual fitter.
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
