class RooImproperIntegrator1D: public RooAbsIntegrator

Special numeric integrator that can handle integrals over open domains. To this end the range is cut in up three pieces: [-inf,-1],[-1,+1] and [+1,inf] and the outer two pieces, if required are calculated using a 1/x transform

Function documentation

void registerIntegrator(RooNumIntFactory& fact)
 Register RooImproperIntegrator1D, its parameters and capabilities with RooNumIntFactory
 Default constructor
RooImproperIntegrator1D(const RooAbsFunc& function)
 Constructor with function binding. The integration range is taken from the
 definition in the function binding
RooImproperIntegrator1D(const RooAbsFunc& function, const RooNumIntConfig& config)
 Constructor with function binding and configuration object. The integration range is taken
 from the definition in the function binding
RooImproperIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, const RooNumIntConfig& config)
 Constructor with function binding, definition of integration range and configuration object
RooAbsIntegrator* clone(const RooAbsFunc& function, const RooNumIntConfig& config) const
 Return clone of integrator with given function and configuration. Needed by RooNumIntFactory.
void initialize(const RooAbsFunc* function = 0)
 Initialize the integrator, construct and initialize subintegrators
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 if the limits are valid. For this integrator all limit configurations
 are valid, but if the limits change between two calculate() calls it
 may be necessary to reconfigure (e.g. if an open ended range becomes
 a closed range
Double_t integral(const Double_t* yvec = 0)
 Calculate the integral at the given parameter values of the function binding
Bool_t setUseIntegrandLimits(Bool_t flag)
{_useIntegrandLimits = flag ; return kTRUE ; }
Bool_t canIntegrate1D() const
{ return kTRUE ; }
Bool_t canIntegrate2D() const
{ return kFALSE ; }
Bool_t canIntegrateND() const
{ return kFALSE ; }
Bool_t canIntegrateOpenEnded() const
{ return kTRUE ; }
