Detailed Description

Convert Geant4 exceptions to RuntimeError during this class lifetime.

Note that creating a G4RunManagerKernel resets the exception handler, so errors thrown during setup cannot be caught by Celeritas, and this class can only be used after creating the G4RunManager.

Because the underlying Geant4 error handler is thread-local, this class must be scoped to inside each worker thread. Additionally, since throwing from a worker thread terminates the program, an error handler must be specified if used in a worker thread: you should probably use a celeritas::MultiExceptionHandler .
