C++ (Cpp) LuaValue::setReference Examples

Example #1

File: LuaTable.cpp Project: DahBlount/fs2open.github.com

void LuaTableIterator::toNextElement() {
	auto ret = lua_next(_luaState, -2);

	_hasElement = ret != 0;

	if (_hasElement) {
		LuaValue key;
		key.setReference(UniqueLuaReference::create(_luaState, -2));

		LuaValue value;
		value.setReference(UniqueLuaReference::create(_luaState, -1));

		_currentVal = std::make_pair(key, value);

		// Remove value from stack
		lua_pop(_luaState, 1);
	}
}

Example #2

File: LuaValue.cpp Project: bryansee/fs2open.github.com

bool popValue(lua_State* luaState, LuaValue& target, int stackposition, bool remove) {
	if (!internal::isValidIndex(luaState, stackposition)) {
		return false;
	}

	target.setReference(UniqueLuaReference::create(luaState, stackposition));

	if (remove) {
		lua_remove(luaState, stackposition);
	}

	return true;
}
