Detailed Description

Initialize the Geant4Event objects to host generator and MC truth related information.

Geant4 actions to collect the MC particle information.

This action should register all event extension required for the further processing. We want to avoid that every client has to check if a given object is present or not and than later install the required data structures.

These by default are extensions of type: – Geant4PrimaryEvent with multiple interaction sections, one for each interaction This is the MAIN and ONLY information to feed Geant4

– Geant4PrimaryInteraction containing the track/vertex information to create the primary particles for Geant4. This record is build from the Geant4PrimaryEvent information. – Geant4PrimaryMap a map of the Geant4Particles converted to G4PrimaryParticles to ease particle handling later. – Geant4ParticleMap the map of particles created during the event simulation. This map has directly the correct particle offsets, so that the merging of Geant4PrimaryInteraction particles and the simulation particles is easy....
