RooArgSet is a container object that can hold multiple RooAbsArg objects.
Special p.d.f shape that can be used to model the background of D*-D0 mass difference distributions.
Double_t analyticalIntegral(Int_t code, const char *rangeName=0) const
Implements the actual analytical integral(s) advertised by getAnalyticalIntegral.
RooSpan< double > evaluateBatch(std::size_t begin, std::size_t batchSize) const
Evaluate function for a batch of input data points.

Int_t getAnalyticalIntegral(RooArgSet &allVars, RooArgSet &analVars, const char *rangeName=0) const
if (matchArgs(allVars,analVars,dm)) return 1 ;
Double_t evaluate() const
Evaluate this PDF / function / constant. Needs to be overridden by all derived classes.
RooRealVar represents a variable that can be changed from the outside.
A simple container to hold a batch of data values.
Mother of all ROOT objects.
