public void refresh(K key) Implements com.google.common.cache.LoadingCache.refresh. Doc from com.google.common.cache.LoadingCache.refresh. Loads a new value for `key`, possibly asynchronously. While the new value is loading the previous value (if any) will continue to be returned by `get(key)` unless it is evicted.
