C++ iterator interface
WebThe Boost Iterator Library contains two parts. The first is a system of concepts which extend the C++ standard iterator requirements. The second is a framework of components for building iterators based on these extended concepts and includes several useful iterator adaptors. Author(s) Dave Abrahams, Jeremy Siek and Thomas Witt First Release 1.21.0 Webstd::iterator_traits is the type trait class that provides uniform interface to the properties of LegacyIterator types. This makes it possible to implement algorithms only in terms of …
