Detailed Description

It is a simple guard, which "locks" the scope for the Auditor Service is am exception-safe way.

The pattern ensures that "post-action" will be always executed

  StatusCode Algorithm::sysInitialize ()
   {
      AuditorGuard auditor ( this ,
        auditSvc()                ,   
        IAuditor::Initialize      ) ; 
      ...
      StatusCode sc = ... ;
      ...
      return sc ;                  
   }

  StatusCode Algorithm::sysExecute ()
   {
      AuditorGuard auditor ( this       ,
        auditSvc()                      ,   
        IAuditor::execute               ) ; 
      ...
      StatusCode sc = ... ;
      ...
      auditor.setCode ( sc ) ;
      ...
      return sc ;                  
   }
