// $Log: BrRunInfoManager.h,v $
// Revision 1.2  2001/08/10 13:49:00  ouerdane
// Added 2 methods in BrRunInfoManager:
//   Int_t* GetRunNumbers   -> returns the array of registered runs
//   Int_t  GetNumberOfRuns -> returns the number of runs registered
//
// Added a check in BrDbUpdateModule::Event:
//   if the user has not registered initially the run number
//   returned by the event header, then the job will abort.
//   It forces the user to know exactly which runs he wants
//   to analyze at registration time (brRunInfoManager::Register(runNo))
//
// Removed in the same class a reference to BrMainModule in Begin since
// BrDbUpdateModule might be used in another context (if possible).
//
// Revision 1.1.1.1  2001/06/21 14:55:18  hagel
// Initial revision of brat2
//
// Revision 1.3  2001/03/01 23:22:51  cholm
// Added support for ~/.brahmsdbrc file
//
// Revision 1.2  2001/01/29 20:02:34  cholm
// Corrected a few bugs
//
// Revision 1.1  2001/01/19 18:40:45  cholm
// Added the classes BrRunInfo and BrRunInfoManager for user space application
// access to the run database. They are not fully tested yet. I'll do that,
// modify as need and then write to brahms-dev-l explaing what I did and usage.
