 * $Log: dbNodes.cc,v $
 * Revision 1.4  2016/05/24 17:44:16  dmitry
 * first batch of fixes for Coverity findings
 *
 * Revision 1.3  2000/01/27 20:30:40  porter
 * cleaned up dtor & error logic
 *
 * Revision 1.2  2000/01/14 14:49:10  porter
 * set verbose level for checking, added $Id & $Logs, & made node container
 * more robust for interactions with StDbLib
 *
 * Revision 1.1  2000/01/10 20:31:17  porter
 * modified StDbBroker to be an interface to the DB-interface, StDbLib.
 *  - old functionality is retained for the short-term & modifications
 *    are extensions
