Detailed Description

template<typename Iterator, typename DFn>
class boost::gil::dereference_iterator_adaptor< Iterator, DFn >

const [inline]

For some reason operator[] provided by iterator_facade returns a custom class that is convertible to reference We require our own reference because it is registered in iterator_traits
