ROOT 6.07/09 Reference Guide |
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
