Detailed Description

template<typename T, T... INTS>
class bsl::integer_sequence< T, INTS >

The class template std::integer_sequence represents a compile-time sequence of integers. When used as an argument to a function template, the parameter pack Ints can be deduced and used in pack expansion.

#include <bsl/integer_sequence.hpp>
#include <bsl/debug.hpp>

namespace bsl
{
    inline void
    example_integer_sequence_overview() noexcept
    {
        constexpr bsl::uintmax size{6};
        constexpr bsl::uintmax max{5};
        constexpr bsl::uintmax min{0};

        if (bsl::make_index_sequence<6>::size() == size) {
            bsl::print() << "success\n";
        }

        if (bsl::make_index_sequence<6>::max() == max) {
            bsl::print() << "success\n";
        }

        if (bsl::make_index_sequence<6>::min() == min) {
            bsl::print() << "success\n";
        }
    }
}

Template Parameters

T	the type that defines the sequence of integers
INTS	the integers that make up the integer sequence

Member Function Documentation

size()

template<typename T , T... INTS>

static constexpr bsl::uintmax bsl::integer_sequence< T, INTS >::size ( )

inlinestaticnoexcept

Equivalent to sizeof...(INTS)

#include <bsl/integer_sequence.hpp>
#include <bsl/debug.hpp>

namespace bsl
{
    inline void
    example_integer_sequence_size() noexcept
    {
        constexpr bsl::uintmax size{6};

        if (bsl::make_index_sequence<6>::size() == size) {
            bsl::print() << "success\n";
        }
    }
}

Returns

Equivalent to sizeof...(INTS)

max()

template<typename T , T... INTS>

static constexpr T bsl::integer_sequence< T, INTS >::max ( )

inlinestaticnoexcept

Returns the max integer in the sequence.

#include <bsl/integer_sequence.hpp>
#include <bsl/debug.hpp>

namespace bsl
{
    inline void
    example_integer_sequence_max() noexcept
    {
        constexpr bsl::uintmax max{5};

        if (bsl::make_index_sequence<6>::max() == max) {
            bsl::print() << "success\n";
        }
    }
}

Returns

Returns the max integer in the sequence

min()

template<typename T , T... INTS>

static constexpr T bsl::integer_sequence< T, INTS >::min ( )

inlinestaticnoexcept

Returns the min integer in the sequence.

#include <bsl/integer_sequence.hpp>
#include <bsl/debug.hpp>

namespace bsl
{
    inline void
    example_integer_sequence_min() noexcept
    {
        constexpr bsl::uintmax min{0};

        if (bsl::make_index_sequence<6>::min() == min) {
            bsl::print() << "success\n";
        }
    }
}

Returns

Returns the min integer in the sequence
