   7       * \ingroup Gallery
   8       *
   9       * acts as some kind of decorator adding getter methods for getting
  10       * some information straight from the metadata field of the resource object,
  11       * without having to overload the basic GalleryResource object with thousands
  12       * of accessor methods for every single property we might need.
  13       *
  14       * Using this method, we can have a ImageMetadataReader which would provide
  15       * methods like getHeight, getWidth, getBpp etc, and another SoundMetadataReader
  16       * with methods like getFrequency, etc.
  17       *
  18       * The right way to use this class is:
  19       * <pre>
  20       *   $reader = $resource->getResourceMetadataReader();
  21       *   if( $resource->isImage()) {
  22       *      print( "image size: ".$reader->getHeight()."x".$reader->getWidth()." pixels" );
  23       *   }
  24       * </pre>
  25       *
  26       * The method GalleryResource::getResourceMetadataReader() will return the right
  27       * metadata reader class so that we can check the properties of the file. We can either query
  28       * the methods GalleryResource::isImage(), GalleryResource::isVideo(), etc to know which properties
  29       * we can check, or use PHP's function for checking of which type a class is.
