The special metafunctions <code>range_result_iterator</code> and <code>range_reverse_result_iterator</code>
|
||||
are not part of any Range concept, but they are very useful when implementing
|
||||
certain Range classes like <a href="utility_class.html#sub_range"><code>sub_range</code></a>
|
||||
because of their ability to select iterators based on constness.
