/**
 * A customization dealing with cached data.
 *
 * Base interface for all cache customizations. Customizations are code that get attached
 * to a cache which extend and modify its behavior. Typical exceptions are
 * {@link org.cache2k.io.CacheLoader} and the {@link org.cache2k.expiry.ExpiryPolicy}.
 *
 * <p>A customization may implement {@link AutoCloseable} to be notified upon
 * cache shutdown.
