Detailed Description

template<typename TImageContainer, typename TImageFactory>
class DGtal::ImageCacheWritePolicyWT< TImageContainer, TImageFactory >

Aim: implements a 'WT (Write-through)' write policy cache.

Description of template class 'ImageCacheWritePolicyWT'

Write is done synchronously both to the cache and to the disk.

Template Parameters

TImageContainer	an image container type (model of CImage).
TImageFactory	an image factory.

The policy is done with 2 functions:

• writeInPage : for setting a value on an image at a given position given by a point
• flushPage : for flushing the image on disk according to the cache policy
