Construct an iterator.
1) Default constructor.
Value-initializes the underlying iterators, and initializes the pointer to parent
ranges::join_view with
nullptr.
2) Initializes the underlying
outer_ iterator with
std::move(outer), and the pointer to parent
parent_ with
std::addressof(parent); then calls
satisfy().
3) 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 underlying poniter 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> |
