Detailed Description

template<std::forward_iterator Source_iterator_tp, class Make_pair_tp = detail::Make_pair>
class mysql::ranges::Disjoint_pairs_iterator< Source_iterator_tp, Make_pair_tp >

Iterator used by Disjoint_pairs_interface and Disjoint_pairs_view: this yields the disjoint, adjacent pairs of values from the source iterator.

This caches two iterator positions internally. It returns the pairs by value.

Template Parameters

Source_iterator_tp	The source iterator.
Make_pair_tp	Function object that creates a pair from two input values. By default, uses a function object that creates std::pair objects.
