RooArgSet is a container object that can hold multiple RooAbsArg objects.
Class RooBreitWigner is a RooAbsPdf implementation that models a non-relativistic Breit-Wigner shape.
~RooBreitWigner() override
double evaluate() const override
Evaluate this PDF / function / constant. Needs to be overridden by all derived classes.
double analyticalIntegral(Int_t code, const char *rangeName=nullptr) const override
Implements the actual analytical integral(s) advertised by getAnalyticalIntegral.
TObject * clone(const char *newname) const override
Int_t getAnalyticalIntegral(RooArgSet &allVars, RooArgSet &analVars, const char *rangeName=nullptr) const override
Interface function getAnalyticalIntergral advertises the analytical integrals that are supported.
bool canComputeBatchWithCuda() const override
void computeBatch(cudaStream_t *, double *output, size_t nEvents, RooFit::Detail::DataMap const &) const override
Compute multiple values of BreitWigner distribution.
RooRealVar represents a variable that can be changed from the outside.
Mother of all ROOT objects.
