RooArgSet is a container object that can hold multiple RooAbsArg objects.
virtual void compute(cudaStream_t *, Computer, RestrictArr, size_t, const VarVector &, const ArgVector &={})=0
Bifurcated Gaussian p.d.f with different widths on left and right side of maximum value.
Int_t getAnalyticalIntegral(RooArgSet &allVars, RooArgSet &analVars, const char *rangeName=0) const
Interface function getAnalyticalIntergral advertises the analytical integrals that are supported.
void computeBatch(cudaStream_t *, double *output, size_t nEvents, RooFit::Detail::DataMap const &) const
Compute multiple values of BifurGauss distribution.
double evaluate() const
Evaluate this PDF / function / constant. Needs to be overridden by all derived classes.
Double_t analyticalIntegral(Int_t code, const char *rangeName=0) const
