Detailed Description

template<class S, class C, class T>
class lunchbox::IndexIterator< S, C, T >

Counter-based, as opposed to pointer-based, iterator for any container.

Uses curiously recurring template pattern to return proper type from assignment and other operators. Access methods are to be implemented by a subclass using container_ and i_. Furthermore subclasses need to implement the necessary constructors (see LFVectorIterator for example).

Parameters
SCRTP Subclass type
CThe container type
TThe element type
