From bacbade369a5244f9bcc611488b59f3bd4c8a564 Mon Sep 17 00:00:00 2001 From: Tedd Hansen Date: Sat, 12 Jan 2008 14:30:22 +0000 Subject: Major reorganizing of DotNetEngine. Moved common script engine parts to ScriptEngine.Common, only .Net-specific code in DotNetEngine. AppDomains, event handling, event execution queue and multithreading, script load/unload queue, etc has been moved to ScriptEngine.Common. Loads of things has been put into interfaces instead of the specific class. We are now one step closer to ScriptServer, and its very easy to implement new script languages. Just a few lines required to make them a OpenSim script module with all its glory. --- .../ScriptEngine/DotNetEngine/LSLLongCmdHandler.cs | 295 --------------------- 1 file changed, 295 deletions(-) delete mode 100644 OpenSim/Region/ScriptEngine/DotNetEngine/LSLLongCmdHandler.cs (limited to 'OpenSim/Region/ScriptEngine/DotNetEngine/LSLLongCmdHandler.cs') diff --git a/OpenSim/Region/ScriptEngine/DotNetEngine/LSLLongCmdHandler.cs b/OpenSim/Region/ScriptEngine/DotNetEngine/LSLLongCmdHandler.cs deleted file mode 100644 index 1e4dc99..0000000 --- a/OpenSim/Region/ScriptEngine/DotNetEngine/LSLLongCmdHandler.cs +++ /dev/null @@ -1,295 +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 OpenSim 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.
