genie::evtlib Namespace Reference

Classes
class	EventLibraryInterface
	Reads pre-generated events produced by an external generator. On an event-by-event basis, it can accept GENIE input specifying the neutrino and target IDs and neutrino energy and, therefore, it can re-use the upstream GENIE flux and geometry tools. More...
class	EvtLibInteractionListGenerator
struct	EvtLibParticle

class	SimpleRecordList

Functions
void	Expand (std::string &s)
	Expand env vars/homedirs/wildcards in s.

Variables
const int	kEvtLibMaxParts = 1024
	Maximum number of particles supported in a single library event record.
