Detailed Description

template<typename TImageContainer, typename TImageFactory, typename TReadPolicy, typename TWritePolicy>
class DGtal::ImageCache< TImageContainer, TImageFactory, TReadPolicy, TWritePolicy >

Aim: implements an images cache with 'read and write' policies.

Description of template class 'ImageCache'

Template Parameters
TImageContaineran image container type (model of CImage).
TImageFactoryan image factory type (model of CImageFactory).
TReadPolicyan image cache read policy class (model of CImageCacheReadPolicy).
TWritePolicyan image cache write policy class (model of CImageCacheWritePolicy).

The cache provides 3 functions:
