vmpl_sum_constant< ele, boost::mpl::vector< vars ... > > Struct Template Reference

Detailed Description

template<unsigned int ele, typename ... vars>
struct vmpl_sum_constant< ele, boost::mpl::vector< vars ... > >

Take a boost::mpl::vector of boost::mpl::int_ and sum the element ele

vmpl_sum_constant<boost::mpl::vector<boost::mpl::int_<2>,boost::mpl::int_<4>,boost::mpl::int<8>>, 5>::type is converted into

boost::mpl::vector<int_<7>,int_<9>,int_<13>>

    typedef to_boost_vmpl<1,4,5,9>::type bfv;

    typedef vmpl_sum_constant<5,bfv>::type vsc;

    BOOST_REQUIRE_EQUAL(boost::mpl::size<vsc>::type::value,4);

    bool val = std::is_same<boost::mpl::at<vsc,boost::mpl::int_<0>>::type,boost::mpl::int_<6>>::value;
    BOOST_REQUIRE_EQUAL(val,true);

    val = std::is_same<boost::mpl::at<vsc,boost::mpl::int_<1>>::type,boost::mpl::int_<9>>::value;
    BOOST_REQUIRE_EQUAL(val,true);

    val = std::is_same<boost::mpl::at<vsc,boost::mpl::int_<2>>::type,boost::mpl::int_<10>>::value;
    BOOST_REQUIRE_EQUAL(val,true);

    val = std::is_same<boost::mpl::at<vsc,boost::mpl::int_<3>>::type,boost::mpl::int_<14>>::value;
    BOOST_REQUIRE_EQUAL(val,true);
