This file contains the method definitions for the PlasmaMLPALLASRunAction class declared in PlasmaMLPALLASRunAction.hh. It manages:

• Initialization of run-wide ROOT files and trees
• Thread-safe data collection in multi-threaded runs
• Branch creation for all recorded statistics
• Interaction with primary generator and geometry to populate run metadata
• Begin/end-of-run hooks to prepare and finalize data storage

The run action workflow:

• BeginOfRunAction:
  • Locks file access (multi-thread safety)
  • Builds the ROOT output file name based on threading context
  • Creates TTree objects for each statistics category
  • Defines ROOT branches for run-wide parameters and measurements
  • Initializes the random seed
• During the run:
  • Updates statistics via UpdateStatistics() and specialized variants
• EndOfRunAction:
  • Finalizes statistics
  • Writes all TTrees to the ROOT file
  • Closes the file and releases resources

Thread safety is ensured via:

• std::atomic<int> activeThreads for counting active threads
• G4Mutex fileMutex for synchronized file access

Note

This class uses Geant4's ROOT integration to structure physics output in an analysis-friendly format.
