Description aniello.nappi 2006-05-31 12:38:48 CEST 
I have my implementation of G4UserRunAction and I want to change the run ID,
calling G4Run::SetRunID in my implementation of the virtual method
G4UserRunAction::BeginOfRunAction.
However, since the method is declared as
virtual void BeginOfRunAction(const G4Run* aRun)
I get a compiler error for the statement
aRun->SetRunID(id)
I guess the reason is that somehow the compiler understands that I want to
modify G4Run and that is not allowed since the pointer to G4Run is declared as a
const.

Is that a problem or just poor understanding on my side?

It is intentionally set to "const" to avoid any mis-use.
But, given run number is not used in Geant4 kernel, you can
set the number by casting const pointer to non-const pointer.
