NumIter< INT > Class Template Reference

#include "lib/iter-adapter.hpp"

Description

template<typename INT>
class lib::NumIter< INT >

Enumerate all "numbers" within a range.

This allows to build pipelines based on all numbers "for `i` from `1...N`". This range is half open, i.e. the start is inclusive and the end point is exclusive.

Remarks

default constructed iters are empty and compare equal with any other exhausted NumIter; essential requirement for a Lumiera Forward Iterator (allows use in range-for-loops).

Template Parameters

INT	a number like type, which can be incremented and compared.

Note

deliberately yields by-value and has no operator->
