From 1ad237a8a757a0e6074278aff76805d01abf0c0b Mon Sep 17 00:00:00 2001 From: diva Date: Sun, 7 Jun 2009 19:00:55 +0000 Subject: First draft of inventory service connectors, and service implementation. No handlers yet, this is just the OUT part for now. It's not active and nothing in the simulator uses this yet. Just checking it in to start sharing with others. There are a couple of interesting software design points that could use other devs opinions. Hopefully I added all needed files. --- .../Communications/Cache/InventoryFolderImpl.cs | 470 --------------------- 1 file changed, 470 deletions(-) delete mode 100644 OpenSim/Framework/Communications/Cache/InventoryFolderImpl.cs (limited to 'OpenSim/Framework/Communications/Cache/InventoryFolderImpl.cs') diff --git a/OpenSim/Framework/Communications/Cache/InventoryFolderImpl.cs b/OpenSim/Framework/Communications/Cache/InventoryFolderImpl.cs deleted file mode 100644 index 71f6f1b..0000000 --- a/OpenSim/Framework/Communications/Cache/InventoryFolderImpl.cs +++ /dev/null @@ -1,470 +0,0 @@ -/* - * Copyright (c) Contributors, http://opensimulator.org/ - * See CONTRIBUTORS.TXT for a full list of copyright holders. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are met: - * * Redistributions of source code must retain the above copyright - * notice, this list of conditions and the following disclaimer. - * * Redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution. - * * Neither the name of the OpenSimulator Project nor the - * names of its contributors may be used to endorse or promote products - * derived from this software without specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS ``AS IS'' AND ANY - * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED - * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE - * DISCLAIMED.
