Detailed Description

template<class T, size_t N, template< size_t, size_t > class F>
struct generate_array_constexpr< T, N, F >

Main class to generate constexpr compile-time array.

A constexpr compile time array is for example

constexpr size_t array[5] = {1,2,3,4,5}

Metafunction definition

Usage

    const size_t count = 5;
    typedef typename ::generate_array_constexpr<size_t,count, MetaFunc>::result ct_test_ce;

    // ct_test_ce::data is equivalent to constexpr size_t [5] = {5,6,7,8,9}

    const size_t ct_calc = MetaFunc<ct_test_ce::data[0],ct_test_ce::data[1]>::value;
    BOOST_REQUIRE_EQUAL(ct_calc,11ul);

Parameters

T	is the type ot the output array
N	size of the sequence
F	Meta function it take two template arguments
