// FIlterModule.cc -- Illustration of using the ignoreModule and 
//			respondToModule features of ErrorLogger 
//

// -----------------
// Physicsists' Code
// -----------------

#include "IgnoreModule.h"

#include "ErrorLogger/ErrorLog.h"
	// This is the only ErrorLogger-related include the user normally needs.

void DoPhysics1::operator()( Event & event )  {
  errlog( ELerror, "An Event [-1-]" ) << "data = " << event.data << endmsg;
} // DoPhysics1::operator()(event)

void DoPhysics2::operator()( Event & event )  {
  errlog( ELerror, "An Event [-2-]" ) << "data = " << event.data << endmsg;
} // DoPhysics2::operator()(event)

void DoPhysics3::operator()( Event & event )  {
  errlog( ELerror, "An Event [-3-]" ) << "data = " << event.data << endmsg;

// ---------------
// Framework Code
// ---------------

	// The framework would normally include some framework.h, plus Event.h,
	// Module.h, and the headers for any physicist classes like DoPhysics.
	// In our illustration these are all in basicUsage.h.

// These are the ErrorLogger classes used by the typical framework:

#include "ErrorLogger/ELadministrator.h"
#include "ErrorLogger/ELdestControl.h"
#include "ErrorLogger/ELoutput.h"
#include "ErrorLogger/ELstatistics.h"
#include "ErrorLogger/ELerrorList.h"
#include <list>

#include "ZMutility/iostream"
