Detailed Description

template<class T, class Tag = void>
struct cal::integer_iterator< T, Tag >

An RandomAccessIterator that stores an integer value of type T. The dereferenced value of the iterator is the integer itself.

Template Parameters

T	An integer type to be wrapped.
Tag	An arbitrary tag used to distinguish between specializations of this template.
