Detailed Description

Everything in Diluculum is declared in this namespace.

Well, everything but the macros defined in Diluculum/LuaWrappers.hpp (because preprocessor macros don't know what are namespaces.)

Typedef Documentation

typedef std::vector<LuaValue> Diluculum::LuaValueList

A list of LuaValues. Used, for example, to represent the return value of a Lua function call. In this case, the first return value is stored at the 0th vector position, the second return value at the 1st vector position and so on. Definition at line 36 of file Types.hpp.

typedef std::map<LuaValue, LuaValue> Diluculum::LuaValueMap

Type mapping from LuaValues to LuaValues. Think of it as a C++ approximation of a Lua table. Definition at line 48 of file Types.hpp.

Function Documentation

void Diluculum::PushLuaValue (  lua_State *  state, const LuaValue &  value )

Calls the appropriate lua_push*() function, in order to push the value stored at value to the Lua stack. Note: If value holds a table, then any entry that happens to have Nil as key will be ignored.

LuaValue Diluculum::ToLuaValue (  lua_State *  state, int  index )

Converts and returns the element at index index on the stack to a LuaValue. This keeps the Lua stack untouched. Oh, yes, and it accepts both positive and negative indices, just like the standard functions on the Lua C API. Exceptions: LuaTypeError  If the element at index cannot be converted to a LuaValue. This can happen if the value at that position is, for example, a "Lua Thread" that is not supported by LuaValue.

Variable Documentation

const LuaValueMap Diluculum::EmptyLuaValueMap

A constant that is an empty LuaValueMap. Definition at line 286 of file LuaValue.hpp.

const LuaValue Diluculum::EmptyTable(EmptyLuaValueMap)

A constant with value of an empty table.

const LuaValue Diluculum::Nil

A constant with the value of nil. Definition at line 283 of file LuaValue.hpp.
