## Class Description

RooAdaptiveGaussKronrodIntegrator1D()

RooAdaptiveGaussKronrodIntegrator1D(const RooAbsFunc& function, const RooNumIntConfig& config) : RooAbsIntegrator(function), _epsAbs(config.epsRel()), _epsRel(config.epsAbs()), _workspace(0)

     Use this form of the constructor to integrate over the function's default range.

RooAdaptiveGaussKronrodIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, const RooNumIntConfig& config) : RooAbsIntegrator(function), _epsAbs(config.epsRel()), _epsRel(config.epsAbs()), _workspace(0), _xmin(xmin), _xmax(xmax)

     Use this form of the constructor to integrate over the function's default range.

RooAbsIntegrator* clone(const RooAbsFunc& function, const RooNumIntConfig& config) const

Bool_t initialize()

     Allocate coordinate buffer size after number of function dimensions

~RooAdaptiveGaussKronrodIntegrator1D()

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)
