## 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 ;
}
