std::ranges...r::iterator(3)

💖 NAME 💖

okay so bestie, this page is for std::ranges::join_view::iterator::iterator — and yes, the NAME section says std::ranges::join_view::iterator::iterator again 💅. We're in the C++ Standard Libary manual, and the whole vibe is: construct an iterator ✨

✨ Synopsis ✨

Here's the signature lineup, no cap:

/*iterator*/() requires std::default_initializable<OuterIter> &&
  std::default_initializable<InnerIter> = default;
(1) (since C++20)

constexpr /*iterator*/( Parent& parent, OuterIter outer );
(2) (since C++20)

constexpr /*iterator*/( /*iterator*/<!Const> i )
  requires Const &&
    std::convertible_to<ranges::iterator_t<V>, OuterIter> &&
    std::convertible_to<ranges::iterator_t<InnerRng>, InnerIter>;
(3) (since C++20)

Construct an iterator. 🛠️✨ That's the whole assignment.

1. Default constructor 🐣 — value-initializes the underlying iterators, and initializes the pointer to parent ranges::join_view with nullptr.
2. Parent + outer constructor 🌱 — initializes the underlying outer_ iterator with std::move(outer), and the pointer to parent parent_ with std::addressof(parent); then calls satisfy().
3. Conversion constructor 🦋 — conversion from /*iterator*/<false> to /*iterator*/<true>. Move constructs the underlying iterators outer_ with std::move(i.outer_), inner_ with std::move(i.inner_), and the underlying pointer to parent parent_ with i.parent_.

🎀 Parameters 🎀

• parent — a (possibly const-qualified) ranges::join_view
• outer — an iterator into (possibly const-qualified) ranges::iterator_t<Base>
• i — an /*iterator*/<false>
