bool Hadronize(GHepRecord *event) const
Base class for the Pythia (6 and 8) hadronization modules in GENIE. In particular, the base class provides common checks and basic assignments of quark/diquark codes for a no frills interface to Pythia hadronization routines.
void CopyOriginalDecayFlags(void) const
void SetDesiredDecayFlags(void) const
Provides access to the PYTHIA hadronization models. Is a concrete implementation of the EventRecord...
A registry. Provides the container for algorithm configuration parameters.
