class RooFoamGenerator: public RooAbsNumGenerator
Class RooFoamGenerator is a generic toy monte carlo generator that implement the TFOAM sampling technique on any positively valued function. The RooFoamGenerator generator is used by the various generator context classes to take care of generation of observables for which p.d.fs do not define internal methods
