[Opensim-dev] Upcoming work on alternative client stack

[Charles Krinke]

I would suggest the key is not to break existing behavior since there are over a thousand OpenSim sims in existence on several grids and standalone arrays.

I'm not sure I fully understand the issue.

My changes in IClientAPI is to replace Packet with object:

IClientAPI:
-        void InPacket(Packet NewPack);
+        void InPacket(object NewPack);

This way the interface doesn't dictate the datatype of the packet, but
the implementing class does:

LLClientView (implements IClientAPI):
-        public virtual void InPacket(Packet NewPack)
+        public virtual void InPacket(object NewPack)
         {
-            m_PacketHandler.InPacket(NewPack);
+            // Cast NewPack to Packet.
+            m_PacketHandler.InPacket((Packet) NewPack);
         }

Since the interface expects an object, anything can be passed around,
be it byte[], Packet or GenericMessagePacket.

Does that still pose any issues for you?

Mike
