Class Description

 RooSimGenContext is an efficient implementation of the generator context
 specific for RooSimultaneous PDFs when generating more than one of the
 component pdfs.

RooSimGenContext(const RooSimultaneous &model, const RooArgSet &vars, const RooDataSet *prototype, const RooArgSet* auxProto, Bool_t verbose) : RooAbsGenContext(model,vars,prototype,auxProto,verbose), _pdf(&model)

 Constructor. Build an array of generator contexts for each component PDF

~RooSimGenContext()

 Destructor. Delete all owned subgenerator contexts

void initGenerator(const RooArgSet &theEvent)

 Attach the index category clone to the event

void generateEvent(RooArgSet &theEvent, Int_t remaining)

 Generate event appropriate for current index state.
 The index state is taken either from the prototype
 or generated from the fraction threshold table.

void setProtoDataOrder(Int_t* lut)
