// Description:
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
//
// Author(s): Steve Schaffner
//
//  We may want to inline some of these functions some day.
//
// Revision History:
//  20000523  M. Kelsey -- Add concrete printAll() implementation which
//              calls through to subclass print(), then dumps HOT list.
