#ifndef MessageService_ELadministrator_h
#define MessageService_ELadministrator_h

// ----------------------------------------------------------------------
//
// ELadminstrator.h  provides the singleton class that the framework uses to
//		     control logger behavior including attaching destinations.
//		Includes the methods used by ErrorLog to evoke the logging
//		behavior in the destinations owned by the ELadminstrator.
//
// ----------------------------------------------------------------------
//
// ELadministrator   The singleton logger class.  One does not instantiate
//		     an ELadministrator.  Instead, do
//			ELadministrator * logger = ELadministrator::instance();
//		     to get a pointer to the (unique) ELadministrator.
//
//	Only the framework should use ELadministrator directly.
//	Physicist users get at it indirectly through using an ErrorLog
//	set up in their Module class.
//
// ELadminDestroyer  A class whose sole purpose is the destruction of the
//                   ELadministrator when the program is over.  Right now,
//                   we do not have anything that needs to be done when the
//                   ELadministrator (and thus the error logger) goes away;
//                   but since by not deleting the copies of ELdestination's
//                   that were attached we would be left with an apparent
//                   memory leak, we include a protected destructor which will
//                   clean up.  ELadminDestroyer provides the only way for
//                   this destructor to be called.
//
// ----------------------------------------------------------------------
//
// 7/2/98 mf	Created file.
// 2/29/00 mf	Added method swapContextSupplier for ELrecv to use.
// 4/5/00 mf	Added method swapProcess for same reason:  ELrecv wants to
//		be able to mock up the process and reset it afterward.
// 6/6/00 web	Consolidate ELadministrator/X; adapt to consolidated
//		ELcout/X.
// 6/14/00 web	Declare classes before granting friendship.
// 6/4/01  mf	Grant friedship to ELtsErrorLog
// 3/6/02  mf   Items for recovering handles to attached destinations:
//		the attachedDestinations map,
//		an additional signature for attach(),
//		and getELdestControl() method
// 3/17/04 mf	exitThreshold and setExitThreshold
// 1/10/06 mf	finish
