class RooAddGenContext: public RooAbsGenContext
RooAddGenContext is an efficient implementation of the generator context specific for RooAddPdf PDFs. The strategy of RooAddGenContext is to defer generation of each component to a dedicated generator context for that component and to randomly choose one of those context to generate an event, with a probability proportional to its associated coefficient
