Detailed Description

template<typename It, typename Mapper>
class util::mapping_iterator_adapter< It, Mapper >

Allows inline transformations on iterators. When the iterator is dereferenced, it is passed through a unary functor of some kind, and the returned value is the output of this functor. Useful for 'pipelining' operations on iterators, or for adapting ranges when passing them to methods in a way that doesn't require a new range to be allocated
