Class Description

RooSegmentedIntegrator1D()
RooSegmentedIntegrator1D(const RooAbsFunc& function, const RooNumIntConfig& config) : RooAbsIntegrator(function), _config(config) 
 Use this form of the constructor to integrate over the function's default range.
RooSegmentedIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, const RooNumIntConfig& config) : RooAbsIntegrator(function), _config(config) 
 Use this form of the constructor to override the function's default range.
RooAbsIntegrator* clone(const RooAbsFunc& function, const RooNumIntConfig& config) const
Bool_t initialize()
~RooSegmentedIntegrator1D()
Bool_t setLimits(Double_t xmin, Double_t xmax) 
 Change our integration limits. Return kTRUE if the new limits are
 ok, or otherwise kFALSE. Always returns kFALSE and does nothing
 if this object was constructed to always use our integrand's limits.
Bool_t checkLimits() const 
 Check that our integration range is finite and otherwise return kFALSE.
 Update the limits from the integrand if requested.
Double_t integral(const Double_t *yvec)
