3. LuaCOM Elements

LuaCOM is composed by the following elements:

• LuaCOM objects, which make COM objects available in Lua;

• LuaCOM API, a set of functions used to do a variety of tasks (library initialization, object creation, implementation of Automation interfaces in Lua, manipulation of connection points etc.);

• Automation binding, which translates accesses on LuaCOM objects to COM interface calls and COM accesses on an interface implemented in Lua to Lua function calls or table accesses;

• LuaCOM type conversion rules, which govern the type conversion between Lua and Automation types;

• LuaCOM parameter passing rules, which describe how LuaCOM translate a Lua parameter list to a COM one and vice versa;

• other objects, like typelib, typeinfo, enumerator etc.
