Detailed Description

Responsibilities:

  • At event begin: optionally log event/thread identification.
  • At event end:
    • Retrieve the hit collections for the event.
    • For each hit collection:
      • Resolve the digitization routine associated with the collection name.
      • Convert hits into digitized data and true-information data.
      • Add these products to the event data container.
    • Publish the completed event data to all configured streamers for the thread.

Ownership:

  • The run_action pointer is non-owning; it is expected to remain valid for the lifetime of the thread actions (it is created and registered by GAction).

Constructor & Destructor Documentation

◆ GEventAction()

GEventAction::GEventAction ( const std::shared_ptr< GOptions > & gopt,
GRunAction * run_a )
Parameters
goptShared configuration used to construct event data containers and control logging.
run_aNon-owning pointer to the thread's GRunAction instance, used to access digitization routines and the streamer map.

Member Function Documentation

◆ BeginOfEventAction()

void GEventAction::BeginOfEventAction ( const G4Event * event)
override

Typical usage in this module is logging and lightweight per-event bookkeeping.

Parameters
eventThe Geant4 event descriptor.

Definition at line 20 of file gEventAction.cc.

◆ EndOfEventAction()

void GEventAction::EndOfEventAction ( const G4Event * event)
override

This method performs the event-level workflow:

  • Collect hit collections.
  • Digitize hits and collect truth information.
  • Publish the resulting event data to streamers.
Parameters
eventThe Geant4 event descriptor.
