//
// LoggedErrorsSummary.h - Methods to obtain summary of warning and error
//          messages issued in an event.  
//
//   Usage:  
//  EnableLoggedErrorsSummary();
//  then per event:
//  some_code_that_might_issue_messages();
//  if (edm::FreshErrorsExist()) {
//    std::vector<edm::ErrorSummaryEntry> es = edm::LoggedErrorsSummary();
//    package_as_product_in_the_event (es);
//  }
//
//  The above gives warnings and errors; use LoggedErrorsOnlySummary() for
//  just errors.
//
//  Note:  This goes by severity level.  Thus a LogImportant message, though
//         not intended to convey a problematic error, will appear in the
//         summary.  Also, Absolute and System messages are logged.

//
//  void
//  package_as_product_in_the_event(std::vector<edm::ErrorSummaryEntry> const& es)
//  {
//    // This example shows how to save just errors and not warnings
//    std::vector<edm::ErrorSummaryEntry> errs;
//    std::vector<edm::ErrorSummaryEntry>::const_iterator end = es.end();
//    for (std::vector<edm::ErrorSummaryEntry>::const_iterator i = es.begin();
//                                                        i != end; ++i) { 
//      if ( i->severity >= edm:ELerror ) errs.push_back(*i);
//    }
//    place_into_event(errs);
//  }
