| class boost::gil::detail::step_iterator_adaptor< Derived, Iterator, SFn ></h3> |
| |
| An adaptor over an existing iterator that changes the step unit. |
| <p> |
| (i.e. distance(it,it+1)) by a given predicate. Instead of calling base's operators ++, --, +=, -=, etc. the adaptor is using the passed policy object SFn for advancing and for computing the distance between iterators. <table border="0" cellpadding="0" cellspacing="0"> |
