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().
