Detailed Description

Data structure to map particles produced during the generation and the simulation.

This data structure is added to the Geant4Event data extensions by the Geant4GenerationInit action. Particles are added:

• During the generation if the required modules are activated
• At the end of the handling of the MC truth are particles to be kept are inserted if the required modules are activated such as the Geant4ParticleHandler.

Note: This object takes OWNERSHIP of the inserted particles! beware of double deletion of objects!
