genie::GHepVirtualList Class Reference

A GHepVirtualList is a 'virtual' collection of GHepParticles. Is virtual because it does not own but only points to GHepParticles owned by the generated GHepRecord. Use it if in your event generation algorithm you need to define & use a GHepRecord subset (without duplicating the GHepParticle entries) All 'named' lists are managed by the GHepVirtualListFolder singleton and get cleared after the generation of each event is completed.
