12  * $Log: dbNodes.h,v $
13  * Revision 1.5 2001/01/22 18:40:25 porter
14  * Added a wrapper for StMessage so one can use it in StDbLib
15  *
16  * Revision 1.4 2000/01/27 20:30:40 porter
17  * cleaned up dtor & error logic
18  *
19  * Revision 1.3 2000/01/27 05:56:03 porter
20  * update for compiling on CC5+HPUX-aCC+KCC
21  *
22  * Revision 1.2 2000/01/14 14:49:10 porter
23  * set verbose level for checking, added $Id & $Logs, & made node container
24  * more robust for interactions with StDbLib
25  *
26  * Revision 1.1 2000/01/10 20:31:17 porter
27  * modified StDbBroker to be an interface to the DB-interface, StDbLib.
28  * - old functionality is retained for the short-term & modifications
29  * are extensions
