I am looking at implementing some iterators based on the design paradigms
outlined
in
http://www.boost.org/libs/iterator/doc/iterator_facade.html
In the first instance I am not able to use templates at all, but I would
like to
implement it in a template-friendly fashion, and hopefully make it fully
templated
in due course.
My question is why is it recommended to implement
iterator_core_accessfunctions as
private static members of a separtate class rather making them a base class
of iterator_facade
which could be privately inherited and then remove the need to make
iterator_core_access a
friend of Derived?
