      public Object extractFromEntry(Map.Entry entry)
      Description copied from class: AbstractExtractor
      Extract the value from the passed Entry object. The returned value should follow the conventions outlined in the AbstractExtractor.extract(T) method. By overriding this method, an extractor implementation is able to extract a desired value using all available information on the corresponding Map.Entry object and is intended to be used in advanced custom scenarios, when application code needs to look at both key and value at the same time or can make some very specific assumptions regarding to the implementation details of the underlying Entry object.
      Overrides:
      extractFromEntry in class AbstractExtractor
      Parameters:
      entry - an Entry object to provide context to lookup up appropriate resource registry.
      Returns:
      JCache CacheStatistics looked up via entry's context.
