// ErrorObj.cc
//
// History:
//
// Created 7/8/98 mf
// 6/16/99  mf, jvr     ErrorObj::operator<<( void (* f)(ErrorLog &) )
//                      allows an "ErrorObj << endmsg;"
// 7/16/99  jvr         Added setSeverity() and setID functions
// 6/7/00   web         Forbid setting extreme severities; guard against
//                      too-long ID's
// 9/21/00  mf          Added copy constructor for use by ELerrorList
// 5/7/01   mf          operator<< (const char[])
// 6/5/01   mf          setReactedTo
// 11/01/01 web         maxIDlength now unsigned
//
// 2/14/06  mf      Removed oerator<<(endmsg) which is not needed for
//          MessageLogger for CMS
//
// 3/13/06  mf      Instrumented for automatic suppression of spaces.
// 3/20/06  mf      Instrumented for universal suppression of spaces
//          (that is, items no longer contain any space added
//          by the MessageLogger stack)
//
// 4/28/06  mf      maxIDlength changed from 20 to 200
//          If a category name exceeds that, then the
//          limit not taking effect bug will occur again...
//
// 6/6/06  mf       verbatim
//
// ErrorObj( const ELseverityLevel & sev, const ELstring & id )
// ~ErrorObj()
// set( const ELseverityLevel & sev, const ELstring & id )
// clear()
// setModule    ( const ELstring & module )
// setSubroutine( const ELstring & subroutine )
// emitToken( const ELstring & txt )
