Constructor of specialized generator context for RooSimultaneous p.d.f.s.

This context creates a dedicated context for each component p.d.f.s and delegates generation of events to the appropriate component generator context

RooDataSet * RooSimSplitGenContext::generate ( Double_t  nEvents = 0,
Bool_t  skipInit = kFALSE,
Bool_t  extendedMode = kFALSE 
)
virtual

Generate the specified number of events with nEvents>0 and and return a dataset containing the generated events.

With nEvents<=0, generate the number of events in the prototype dataset, if available, or else the expected number of events, if non-zero. If extendedMode = true generate according to a Poisson(nEvents) The returned dataset belongs to the caller. Return zero in case of an error. Generation of individual events is delegated to a virtual generateEvent() method. A virtual initGenerator() method is also called just before the first call to generateEvent().
