From 646bbbc84b8010e0dacbeed5342cdb045f46cc49 Mon Sep 17 00:00:00 2001 From: MW Date: Wed, 27 Jun 2007 15:28:52 +0000 Subject: Some work on restructuring the namespaces / project names. Note this doesn't compile yet as not all the code has been changed to use the new namespaces. Am committing it now for feedback on the namespaces. --- OpenSim/Framework/General/LLSDHelpers.cs | 246 +++++++++++++++++++++++++++++++ 1 file changed, 246 insertions(+) create mode 100644 OpenSim/Framework/General/LLSDHelpers.cs (limited to 'OpenSim/Framework/General/LLSDHelpers.cs') diff --git a/OpenSim/Framework/General/LLSDHelpers.cs b/OpenSim/Framework/General/LLSDHelpers.cs new file mode 100644 index 0000000..051520c --- /dev/null +++ b/OpenSim/Framework/General/LLSDHelpers.cs @@ -0,0 +1,246 @@ +using System;
