Let inner_ denote the underlying iterator.
1,2) Returns the iterator i incremented by n. Equivalent to:
return
/*iterator*/
(
*i.parent_, i.inner_
+ n)
;
3) Returns the iterator
i decremented by n. Equivalent to:
return
/*iterator*/
(
*i.parent_, i.inner_
- n)
;
4) Calculates the distance between i and j. Equivalent to return i.inner_ - j.inner_;
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when zip_transform_view::iterator<Const>
Parameters
| i, j | - | the iterators |
| n | - | position relative to current location |
Return value
1,2)
/*iterator*/{ inner_ + n }
3)
/*iterator*/{ inner_ - n }
4) i.inner_ - j.inner_
