28// Class description:
29//
30// This is an abstract base class for persistency management. The user's
31// concrete class derived from this class must act as a singleton. The user
32// must construct the object of his/her concrete persistency manager in
33// the main().
34// The virtual methods of Store() and Retrieve() will be invoked from
35// G4RunManager if the persistency manager exists.
36// Even if the user does not use any ODBMS system, the user can use this
37// class especially for Store() methods. Writing an ASCII file for storing
38// event information can be delegated to this class, for example.
