Detailed Description

template<typename TSpace, typename TStorageOrder>
struct DGtal::Linearizer< HyperRectDomain< TSpace >, TStorageOrder >

Aim: Linearization and de-linearization interface for HyperRectDomain.

This is a static class that provides point linearization (point to index) and de-linearization (index to point) for storages working on HyperRectDomain.

The storage order can be specified by template (default is colum-major ordered).

Example:

typedef SpaceND<2>             Space;
tydedef HyperRectDomain<Space> Domain;
typedef typename Space::Point  Point;
 
const Domain domain( Point(0, 1), Point(4, 3) );
 
typename Linearizer<Domain>::Size id = Linearizer<Domain>::getIndex( Point(2, 2), domain ); // returns 7.
 
Point pt = Linearizer<Domain>::getPoint( 7, domain); // returns Point(2,2).

Template Parameters

TSpace	Type of the space of the HyperRectDomain (auto-deduced from TDomain template, see Linearizer).
TStorageOrder	Storage Order (RowMajorStorage of ColMajorStorage).
