Function documentation
void registerIntegrator(RooNumIntFactory& fact)
Register RooIntegrator2D, is parameters and capabilities with RooNumIntFactory
RooIntegrator2D(const RooAbsFunc& function, RooIntegrator1D::SummationRule rule = RooIntegrator1D::Trapezoid, Int_t maxSteps = 0, Double_t eps = 0)
Constructor with a given function binding, summation rule, maximum number of steps and conversion tolerance. The integration limits are taken from the definition in the function binding.
RooIntegrator2D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, Double_t ymin, Double_t ymax, RooIntegrator1D::SummationRule rule = Trapezoid, Int_t maxSteps = 0, Double_t eps = 0)
Constructor with a given function binding, summation rule, maximum number of steps, conversion tolerance and an explicit choice of integration limits on both dimensions.
RooIntegrator2D(const RooAbsFunc& function, const RooNumIntConfig& config)
Constructor with a function binding and a configuration object. The integration limits are taken from the definition in the function binding
RooIntegrator2D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, Double_t ymin, Double_t ymax, const RooNumIntConfig& config)
Constructor with a function binding, a configuration object and an explicit definition of the integration limits.
RooAbsIntegrator* clone(const RooAbsFunc& function, const RooNumIntConfig& config) const
Clone integrator with new function and configuration. Needed to support RooNumIntFactory
Bool_t checkLimits() const
Verify that the limits are OK for this integrator (i.e. no open-ended ranges)
