Function documentation

void registerIntegrator(RooNumIntFactory& fact)

 Register RooSegmentedIntegrator1D, its parameters, dependencies and capabilities with RooNumIntFactory

RooSegmentedIntegrator1D()

 Destructor

RooSegmentedIntegrator1D(const RooAbsFunc& function, const RooNumIntConfig& config)

 Constructor of integral on given function binding and with given configuration. The
 integration limits are taken from the definition in the function binding

RooSegmentedIntegrator1D(const RooAbsFunc& function, Double_t xmin, Double_t xmax, const RooNumIntConfig& config)

 Constructor integral on given function binding, with given configuration and
 explicit definition of integration range

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

 Virtual constructor with given function and configuration. Needed by RooNumIntFactory

Bool_t initialize()

 One-time integrator initialization

~RooSegmentedIntegrator1D()

 Destructor

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 = 0)

 Evaluate integral at given function binding parameter values

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 kFALSE ; }
