[luabind] "Binding" class objects?

[Tyler O. <ro...@al...>]

I've read through the docs but I'm not sure how to go about this 
implementation. Lets say I have a C++ class "AudioEngine", which I 
properly bound to Lua. I have an instance of this class in C++-land 
called "AudioManager", which I want to make available for Lua to use. 
How would one go about doing this?


I -have- managed to achieve my desired result in the case where there is 
a Lua file that the state represents. All you have to do is define a 
variable "AudioEngine" in the file and write a Lua function that takes a 
parameter and sets the AudioEngine variable, then call that Lua function 
from C++. However, I would like to do this when there is no Lua file 
that the state represents.


Has anyone implemented such an "object binding" before? I have to admit 
I'm a bit of a neophyte when it comes to raw manipulation of the Lua 
state... Thanks in advance. :)
