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 = 0;
int iunhandledOrderList = 0;
int istatus = 0;
int ibindFace = 0;
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一样类型值的集合，是泛化的std::pair。和c#中的tuple相似，可是比c#中的tuple强大得多。咱们也能够把他当作一个通用的结构体来用，不须要建立结构体又获取结构体的特征，在某些状况下能够取代结构体使程序更简洁，直观。
