Detailed Description

template<class BaseIterator, class TransformingFunctor>
struct Chusov::Memory::transforming_iterator< BaseIterator, TransformingFunctor >

An adapter for iterators to perform a given transformation upon each access to an iterated object.

Template Parameters

BaseIterator	is an iterator to be adapted.
TransformingFunctor	is the transforming functor.

Dereferencing the adapter for some iterator it and the functor fn is equivalent to the call fn(*it);.
