Detailed Description

Translate Celeritas C++ exceptions into Geant4 G4Exception calls.

This should generally be used when wrapping calls to Celeritas in a user application.

For example, the user event action to transport particles on device could be used as:

void EventAction::EndOfEventAction(const G4Event*)
{
// Transport any tracks left in the buffer
celeritas::ExceptionConverter call_g4exception{"celer0003"};
CELER_TRY_HANDLE(transport_->Flush(), call_g4exception);
}
CELER_TRY_HANDLE
#define CELER_TRY_HANDLE(STATEMENT, HANDLE_EXCEPTION)
"Try" to execute the statement, and "handle" all thrown errors by calling the given function-like err...
