The boost::iterators::advance function template is an adapted
version of std::advance for the Boost iterator traversal
concepts.
<boost/iterator/advance.hpp>
template <typename Iterator, typename Distance> constexpr void advance(Iterator& it, Distance n);
Moves it forward by n increments (or backward by |n|
decrements if n is negative).
Iterator should model Incrementable
Iterator.
Let iti be
the iterator obtained by incrementing (or decrementing if n
is negative) it by i. All the iterators iti for i
= 0, 1, 2, ..., |n| should be valid.
If Iterator does not model
Bidirectional Traversal
Iterator, n should
be non-negative.
If Iterator models Random Access Traversal
Iterator, it takes constant time; otherwise it takes linear time.
constexpr
only in C++14 or later.
