// LuaState.h
|
|
|
|
// Declares the cLuaState class representing the wrapper over lua_State *, provides associated helper functions
|
|
|
|
/*
|
|
The contained lua_State can be either owned or attached.
|
|
Owned lua_State is created by calling Create() and the cLuaState automatically closes the state
|
|
Or, lua_State can be attached by calling Attach(), the cLuaState doesn't close such a state
|
|
Attaching a state will automatically close an owned state.
|
|
|
|
Calling a Lua function is done by pushing the function, either by PushFunction() or PushFunctionFromRegistry(),
|
|
then pushing the arguments (PushString(), PushNumber(), PushUserData() etc.) and finally
|
|
executing CallFunction(). cLuaState automatically keeps track of the number of arguments and the name of the
|
|
function (for logging purposes), which makes the call less error-prone.
|
|
|
|
Reference management is provided by the cLuaState::cRef class. This is used when you need to hold a reference to
|
|
any Lua object across several function calls; usually this is used for callbacks. The class is RAII-like, with
|
|
automatic resource management.
