35 // This is the abstract base class for instantiating all the user action classes.
36 // It has a pure virtual method Build() which is invoked by G4RunManager for
37 // sequential execution and G4WorkerRunManager for multi-threaded execution.
38 // The additional virtual method BuildForMaster() will be invoked from G4MTRunManager
39 // for multi-threaded execution.
40 //
41 // Note that these virtual methods are const. It means the user may construct
42 // user action objects, but should not store the pointers of these objects as
43 // data members of the derived class.
44 //
45 // Note for multi-threaded mode:
46 // The only action class the user may set to G4MTRunManager is a run action. It is
47 // then used at the beginning and the end of a run. It may be the same class or a
48 // dedicated class different from the run action instantiated for G4WorkerRunManager.
