Function documentation

void registerIntegrator(RooNumIntFactory& fact)

 Register RooIntegrator2D, is parameters and capabilities with RooNumIntFactory

RooIntegrator2D()

 Default constructor

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

~RooIntegrator2D()

 Destructor

Bool_t checkLimits() const

 Verify that the limits are OK for this integrator (i.e. no open-ended ranges)
