C++11新特性之tie、tuple的应用

//tuple
std::tuple<int, int, int, int, QString> Thorface::getUserInfoToJudgeOpendoor(QString strUserCode)
{
int iunpaidOrderList = ;
int iunhandledOrderList = ;
int istatus = ;
int ibindFace = ;
QString strUserName = "";
    return std::make_tuple(iunpaidOrderList, iunhandledOrderList, istatus, ibindFace, strUserName);
}

//tie解析
                int iunpaidOrderList = 0;
                int iunhandledOrderList = 0;
                int istatus = -1;
                int ibindFace = -1;
                QString strUserName = "";
                std::tie(iunpaidOrderList, iunhandledOrderList, istatus, ibindFace, strUserName) = getUserInfoToJudgeOpendoor(strName);

tuple是一个固定大小的不同类型值的集合，是泛化的std::pair。和c#中的tuple类似，但是比c#中的tuple强大得多。我们也可以把他当做一个通用的结构体来用，不需要创建结构体又获取结构体的特征，在某些情况下可以取代结构体使程序更简洁，直观。
