Abstract Value Members

  1. abstract def apply(key: K, genValue: () ⇒ Future[V]): Future[V]

    Returns either the cached Future for the given key or evaluates the given value generating function producing a Future[V].

  2. abstract def clear(): Unit

    Clears the cache by removing all entries.

    Clears the cache by removing all entries.

  3. abstract def get(key: K): Option[Future[V]]

    Retrieves the future instance that is currently in the cache for the given key.

    Retrieves the future instance that is currently in the cache for the given key. Returns None if the key has no corresponding cache entry.

  4. abstract def keys: Set[K]

    Returns the set of keys in the cache, in no particular order Should return in roughly constant time.

    Returns the set of keys in the cache, in no particular order Should return in roughly constant time. Note that this number might not reflect the exact keys of active, unexpired cache entries, since expired entries are only evicted upon next access (or by being thrown out by a capacity constraint).

  5. abstract def remove(key: K): Unit

    Removes the cache item for the given key.

    Removes the cache item for the given key.

  6. abstract def size(): Int

    Returns the upper bound for the number of currently cached entries.

    Returns the upper bound for the number of currently cached entries. Note that this number might not reflect the exact number of active, unexpired cache entries, since expired entries are only evicted upon next access (or by being thrown out by a capacity constraint).
