CL_LuaReference(

void)

Description:

Create a reference to a nil object (default)

CL_LuaReference(

const CL_LuaObject& obj,
int lock=0)

Parameters:
lock - to lock or not to lock, that is the question

Description:

Create a reference to the given Lua object An optinal parameter specifies if the reference is not to be garbage collected by Lua. The default, {lock=0}, means the reference becomes invalid if Lua collects the referenced object.

void ref(

const CL_LuaObject& obj,
int lock=0)

Description:

Replace the reference This method allows the user to replace the referenced object; it is useful when the object is created with the default constructor. _Note_: if there is already a reference to a non-'nil' object, this reference, if not used by other LuaReference objets, should be eliminated (using the 'unref' method) before calling this method.

void unref(

void)

Description:

Unreference an object
