template<class Self_tp, class Make_pair_tp>
class mysql::ranges::Disjoint_pairs_interface< Self_tp, Make_pair_tp >
CRTP base used to define classes that yield disjoint, adjacent pairs of elements from an even-length source sequence.
For example, if the source sequence is 2, 3, 5, 7, 11, 13, then this yields the pairs <2,3>, <5,7>, <11,13>. It is conceptually similar to std::stride_view<std::slide_view<Source_tp>>, except the window width is defined at compile time and each window is wrapped in an object.
This is for objects that own the source. If you need objects that do not own the source - a view - use Disjoint_pairs_view.
- Template Parameters
-
| Self_tp | Class that derives from this class. It must implement the member function disjoint_pairs_source(), returning a reference to an object with the member functions begin, end, empty, and size. The distance between begin and end must be even. |
| Make_pair_tp | Class containing a static member function make_pair that defines how to construct a pair from two adjacent elements. By default, uses detail::Make_pair, for which make_pair constructs and returns a std::pair object. |
