RangeIter< IT > Class Template Reference

#include "lib/iter-adapter.hpp"

Description

template<class IT>
class lib::RangeIter< IT >

Accessing a STL element range through a Lumiera forward iterator, An instance of this iterator adapter is completely self-contained and allows to iterate once over the range of elements, until pos==end.

Thus, a custom container may expose a range of elements of an embedded STL container, without controlling the details of the iteration (as is possible using the more generic IterAdapter).

Note

• when IT is just a pointer, we use the pointee as value type
• but when IT is a class, we expect the usual STL style nested typedefs value_type, reference and pointer

value_type

using value_type = typename std::remove_reference<reference>::type

Note

special twist, since a STL const_iterator would yield a non-const value_type
