Detailed Description

Convert Geant4 exceptions to RuntimeError during this class lifetime.

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 if used inside a worker thread.

Note

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.
