Detailed Description

HepMC3 reader class for sharing across threads.

This singleton is shared among threads so that events can be correctly split up between them, being constructed the first time instance() is invoked. As this is a derived G4VPrimaryGenerator class, the HepMC3PrimaryGenerator must be used by a concrete implementation of the G4VUserPrimaryGeneratorAction class:

void PrimaryGeneratorAction::GeneratePrimaries(G4Event* event)
{
    HepMC3PrimaryGenerator::Instance()->GeneratePrimaryVertex(event);
}
