constexpr auto begin();
(1)
(since C++20)
constexpr auto begin() const
requires ranges::forward_range <V> && ranges::forward_range <const V>;
(2)
(since C++20)
requires ranges::forward_range <V> && ranges::forward_range <const V>;
Returns an outer_iterator
to the first element of the lazy_split_view
.
Let base_
be the underlying view and current_
be the underlying caching object (may not be present).
1) Equivalent to
constexpr auto begin() { if constexpr (ranges::forward_range <V>) return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::begin (base_)}; else { current_ = ranges::begin (base_); return /*outer_iterator*/<false>{*this}; } }
2) Equivalent to return /*outer_iterator*/<true>{*this, ranges::begin (base_)};.
[edit] Return value
outer_iterator
to the first element.
