ROOT 6.14/05 Reference Guide |
RooConvGenContext is an efficient implementation of the generator context specific for RooAbsAnaConvPdf objects.
The physics model is generated with a truth resolution model and the requested resolution model is generated separately as a PDF. The convolution variable of the physics model is subsequently explicitly smeared with the resolution model distribution.

Constructor for specialized generator context for FFT numerical convolutions.
Builds a generator for the physics PDF convoluted with the truth model and a generator for the resolution model as PDF. Events are generated by sampling events from the p.d.f and smearings from the resolution model and adding these to obtain a distribution of events consistent with the convolution of these two. The advantage of this procedure is so that both p.d.f and resolution model can take advantage of any internal generators that may be defined.
