IndexIter< CON, PTR > Class Template Reference

#include "lib/index-iter.hpp"

Description

template<class CON, typename PTR = CON*>
class lib::IndexIter< CON, PTR >

Subscript-index based access to a container, packaged as iterator.

This is a copyable and assignable value object (handle), referring to some data container maintained elsewhere. The container must provide an operator[]. This handle can be used as »Lumiera Forward Iterator«, but with the additional capability to retrieve and re-set the current index position.

Template Parameters

CON	a container with operator[] and a function size()
PTR	how to refer to this container; can be defined as smart-ptr, additionally allowing to manage this container automatically.

Remarks

while a default constructed IndexIter and some exhausted IndexIter compare equal, only the latter can be re-set into active state.
