Class Description

 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.

RooConvGenContext(const RooAbsAnaConvPdf &model, const RooArgSet &vars, const RooDataSet *prototype, const RooArgSet* auxProto, Bool_t verbose) : RooAbsGenContext(model,vars,prototype,auxProto,verbose)

 Constructor for analytical convolutions.

 Build a generator for the physics PDF convoluted with the truth model
 and a generator for the resolution model as PDF.

RooConvGenContext(const RooNumConvPdf &model, const RooArgSet &vars, const RooDataSet *prototype, const RooArgSet* auxProto, Bool_t verbose) : RooAbsGenContext(model,vars,prototype,auxProto,verbose)

 Constructor for numeric convolutions.

 Build a generator for the physics PDF convoluted with the truth model
 and a generator for the resolution model as PDF.

~RooConvGenContext()

   cout << "RooConvGenContext::dtor(" << this << "," << GetName() << ")" << endl ;

void printToStream(ostream &os, PrintOption opt, TString indent) const

void initGenerator(const RooArgSet &theEvent)

 Initialize genertor for this event holder

void generateEvent(RooArgSet &theEvent, Int_t remaining)

 Generate a single event of the product by generating the components
 of the products sequentially

void setProtoDataOrder(Int_t* lut)
