Let current_ be the underlying array of iterators, and Base
1,2) Returns the iterator i incremented by n.
Equivalent to:
auto r = i; r +
= n;
return r;
3) Returns the iterator i decremented by n.
Equivalent to:
auto r = i; r -
= n;
return r;
4) Returns the distance between i and j.
Equivalent to:
return i.current_.back
(
)
- j.current_.back
(
)
;
These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when adjacent_view::iterator<Const>
Parameters
| i, j | - | the iterators |
| n | - | position relative to current location |
Return value
1,2) An incremented iterator.
3) A decremented iterator.
4) A distance between given iterators.
