public class NullFilesCache extends AbstractFilesCache
FilesCache
implementation.
This implementation never ever caches a single file.
Notice: if you use resolveFile(uri) multiple times with the same path, the system will always create a new instance. Changes on one instance of this file are not seen by the others.
