      void prefetch(Runnable valueUpdater)

    • fetch

      default <T> RefreshResult<T> fetch(Supplier<RefreshResult<T>> supplier)
      Invoke the provided supplier to retrieve the refresh result. This is useful for prefetch strategies to override when they care about the refresh result.

    • initializeCachedSupplier

      default void initializeCachedSupplier(CachedSupplier<?> cachedSupplier)
      Invoked when the prefetch strategy is registered with a CachedSupplier.

    • close

      default void close()
      Free any resources associated with the strategy. This is invoked when the CachedSupplier.close() method is invoked.
