class RooGenContext: public RooAbsGenContext
Class RooGenContext implement a universal generator context for all RooAbsPdf classes that do not have or need a specialized generator context. This generator context queries the input p.d.f which observables it can generate internally and delegates generation of those observables to the p.d.f if it deems that safe. The other observables are generated use a RooAcceptReject sampling technique.

Function documentation
RooGenContext(const RooAbsPdf& model, const RooArgSet& vars, const RooDataSet* prototype = 0, const RooArgSet* auxProto = 0, Bool_t verbose = kFALSE, const RooArgSet* forceDirect = 0)
Initialize a new context for generating events with the specified variables, using the specified PDF model. A prototype dataset (if provided) is not cloned and still belongs to the caller. The contents and shape of this dataset can be changed between calls to generate() as long as the expected columns to be copied to the generated dataset are present. Any argument supplied in the forceDirect RooArgSet are always offered for internal generation to the p.d.f., even if this is deemed unsafe by the logic of RooGenContext.
void attach(const RooArgSet& params)
Attach the cloned model to the event buffer we will be filling.
void initGenerator(const RooArgSet& theEvent)
Perform one-time initialization of the generator context
void generateEvent(RooArgSet& theEvent, Int_t remaining)
Generate one event. The 'remaining' integer is not used other than for printing messages
void printMultiline(ostream& os, Int_t content, Bool_t verbose = kFALSE, TString indent = "") const
