Question

Would it be possible using Lua and SWIG and say an IInterface class, to implement that interface and instantiate it all within Lua? If so how would it be done?

Answer 1

Store the table in a c++ class by holding a pointer to the lua state, and the reference returned for the table as specified using this API:

http://www.lua.org/pil/27.3.2.html

Then when a method on the wrapper class is called, push the referenced object onto the stack and do the necessary function call
