Let parent_ and inner_ be the data members of the iterator
1,2) Equivalent to
return
/*iterator*/
(
*i.parent_, i.inner_
+ n)
;
3) Equivalent to
return
/*iterator*/
(
*i.parent_, i.inner_
- n)
;
4) Equivalent to return i.inner_ - j.inner_;
These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when adjacent_transform_view::iterator<Const>
Parameters
| i, j | - | the iterators |
| n | - | a position relative to current location |
Return value
1,2) An incremented iterator.
3) A decremented iterator.
4) A distance between given iterators.
