 Return the vector of subimages associated with with pixel frame data; it depends by the application whether it is initialized or not.
 
bool hasPixFrameDataCache (const std::string &fileName, size_t numFrames) const
 If there is a pixel data cache for file name with numFrames then it returns true, otherwise false.

 Clears the entrie(s) of the MLDICOMCachedIOPixelFrameCacheContainer which belong to fileName.
 
void clear ()
 Clears the MLDICOMCachedIOPixelFrameCacheContainer, the pixel frame caches, and resets all counters.

Detailed Description

Structure containing a container for pixel frames and an index of the most recently used one.

. It also contains a recent frame data cache for multi-frame pixel data. These two functionalities in the future should be separated into different classes for nicer modularity.
