$Log$
Revision 1.1.6.1 2003/03/23 21:03:52 dgrisby
Start of omniORB 4.1.x development branch.
Revision 1.1.4.3 2001/08/15 10:26:09 dpg1
New object table behaviour, correct POA semantics.
Revision 1.1.4.2 2001/05/29 17:03:49 dpg1
In process identity.
Revision 1.1.4.1 2001/04/18 17:18:18 sll
Big checkin with the brand new internal APIs.
These files were relocated and scoped with the omni namespace.
Revision 1.2.2.1 2000/07/17 10:35:51 sll
Merged from omni3_develop the diff between omni3_0_0_pre3 and omni3_0_0.
Revision 1.3 2000/07/13 15:25:58 dpg1
Merge from omni3_develop for 3.0 release.
Revision 1.1.2.3 2000/06/02 14:20:15 dpg1
Using boa_lock for the nil BOA's condition variable caused an
assertion failure on exit.
Revision 1.1.2.2 1999/09/28 10:54:33 djr
Removed pretty-printing of object keys from object adapters.
Revision 1.1.2.1 1999/09/22 14:26:45 djr
Major rewrite of orbcore to support POA.
