Detailed Description

Simple interface for G4VUserTrackingAction-based integration.

This singleton integrates both thread-local and global data with the user application. To use this class in your Geant4 application to offload tracks to Celeritas:

• Set up the Options before calling G4RunManager::Initialize
• Call BeginOfRunAction and EndOfRunAction from UserRunAction
• Call BeginOfEvent and EndOfEvent from UserEventAction
• Call PreUserTrackingAction from your UserTrackingAction

The CELER_DISABLE environment variable, if set and non-empty, will disable offloading so that Celeritas will not be built nor kill tracks.

The method names correspond to methods in Geant4 User Actions and must be called from all threads, both worker and master.

Note

Prefer to use celeritas::TrackingManagerIntegration instead of this class, unless you need support for Geant4 earlier than 11.1.

Todo:

Provide default minimal action initialization classes for user?
