## Class Description

RooImproperIntegrator1D()

RooImproperIntegrator1D(const RooAbsFunc& function) : RooAbsIntegrator(function), _useIntegrandLimits(kTRUE), _origFunc((RooAbsFunc*)&function), _function(0), _integrator1(0), _integrator2(0), _integrator3(0)

RooImproperIntegrator1D(const RooAbsFunc& function, const RooNumIntConfig& config) : RooAbsIntegrator(function), _useIntegrandLimits(kTRUE), _origFunc((RooAbsFunc*)&function), _function(0), _config(config), _integrator1(0), _integrator2(0), _integrator3(0)

RooImproperIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, const RooNumIntConfig& config) : RooAbsIntegrator(function), _xmin(xmin), _xmax(xmax), _useIntegrandLimits(kFALSE), _origFunc((RooAbsFunc*)&function), _function(0), _config(config), _integrator1(0), _integrator2(0), _integrator3(0)

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

void initialize(const RooAbsFunc* function)

~RooImproperIntegrator1D()

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

     Analyze the current limits to see if the same case applies.

Double_t integral(const Double_t* yvec)
