object FutureCache

The FutureCache object provides the public interface for constructing FutureCaches. Once you've constructed a basic FutureCache, you should almost always wrap it with default. Normal usage looks like:

val fn: K => Future[V] val map = (new java.util.concurrent.ConcurrentHashMap[K, V]()).asScala val cachedFn: K => Future[V] = FutureCache.default(fn, FutureCache.fromMap(map))

We typically recommend that you use Caffeine Caches via com.twitter.cache.caffeine.CaffeineCache.

  6. def default[K, V](fn: (K) => Future[V], cache: FutureCache[K, V]): (K) => Future[V]

    Creates a function which caches the results of fn in an com.twitter.cache.FutureCache.

    Creates a function which caches the results of fn in an com.twitter.cache.FutureCache. Ensures that failed Futures are evicted, and that interrupting a Future returned to you by this function is safe.
