Detailed Description

template<class T>
class slip::const_iterator2d_range< T >

This is some iterator to iterate a 2d container into two Range defined by the indices and strides of the 2d container.

Author: Benoit Tremblais <tremblais_AT_sic.univ-poitiers.fr>

Version: 0.0.3

Date: 2007/12/15

Parameters

Container2D Type of 2d container in the const_iterator2d_range

Description:: This iterator is an 2d extension of the random_access_iterator. It is compatible with the bidirectional_iterator of the Standard library. It iterate into a range area defined inside the indices range of the 2d container. Those indices are defined as follows :
(0,0)--------> x2 (or j)

|

|

|

|

\|/

x1 (or i)

(0,0) is the upper left corner of the 2d container.
