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>
is an associated class of the arguments.
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
