class RooConvGenContext: public RooAbsGenContext
RooConvGenContext is an efficient implementation of the generator context specific for RooAbsAnaConvPdf objects. The physics model is generated with a truth resolution model and the requested resolution model is generated separately as a PDF. The convolution variable of the physics model is subsequently explicitly smeared with the resolution model distribution.

Function documentation

RooConvGenContext(const RooAbsAnaConvPdf &model, const RooArgSet &vars, const RooDataSet *prototype, const RooArgSet* auxProto, Bool_t verbose)
 Constructor for specialized generator context for analytical convolutions.

 Builds a generator for the physics PDF convoluted with the truth model
 and a generator for the resolution model as PDF. Events are generated
 by sampling events from the p.d.f and smearings from the resolution model
 and adding these to obtain a distribution of events consistent with the
 convolution of these two. The advantage of this procedure is so that
 both p.d.f and resolution model can take advantage of any internal
 generators that may be defined.
RooConvGenContext(const RooNumConvPdf &model, const RooArgSet &vars, const RooDataSet *prototype, const RooArgSet* auxProto, Bool_t verbose)
 Constructor for specialized generator context for numerical convolutions.

 Builds a generator for the physics PDF convoluted with the truth model
 and a generator for the resolution model as PDF. Events are generated
 by sampling events from the p.d.f and smearings from the resolution model
 and adding these to obtain a distribution of events consistent with the
 convolution of these two. The advantage of this procedure is so that
 both p.d.f and resolution model can take advantage of any internal
 generators that may be defined.
RooConvGenContext(const RooFFTConvPdf &model, const RooArgSet &vars, const RooDataSet *prototype, const RooArgSet* auxProto, Bool_t verbose)
 Constructor for specialized generator context for FFT numerical convolutions.

 Builds a generator for the physics PDF convoluted with the truth model
 and a generator for the resolution model as PDF. Events are generated
 by sampling events from the p.d.f and smearings from the resolution model
 and adding these to obtain a distribution of events consistent with the
 convolution of these two. The advantage of this procedure is so that
 both p.d.f and resolution model can take advantage of any internal
 generators that may be defined.
~RooConvGenContext()
 Destructor
void attach(const RooArgSet& params)
 Attach given set of arguments to internal clones of
 pdf and resolution model
void initGenerator(const RooArgSet& theEvent)
 One-time initialization of generator context, attaches
 the context to the supplied event container
void generateEvent(RooArgSet& theEvent, Int_t remaining)
 Generate a single event
void setProtoDataOrder(Int_t* lut)
 Set the traversal order for events in the prototype dataset
 The argument is a array of integers with a size identical
 to the number of events in the prototype dataset. Each element
 should contain an integer in the range 1-N.
void printMultiline(ostream& os, Int_t content, Bool_t verbose = kFALSE, TString indent = "") const
 Print the details of this generator context
RooConvGenContext(const RooFFTConvPdf &model, const RooArgSet &vars, const RooDataSet *prototype= 0, const RooArgSet* auxProto=0, Bool_t _verbose= kFALSE)
