class Keyed extends AnyRef

Abstract Value Members

abstract def apply(key: Any, genValue: () ⇒ Future[V])(implicit ec: ExecutionContext): Future[V]

Returns either the cached Future for the given key or evaluates the given value generating function producing a Future[V].
abstract def ascendingKeys(limit: Option[Int] = None): Iterator[Any]

Returns a snapshot view of the keys as an iterator, traversing the keys from the least likely to be retained to the most likely.
Returns a snapshot view of the keys as an iterator, traversing the keys from the least likely to be retained to the most likely. Note that this is not constant time.
limit
No more than limit keys will be returned
abstract def clear(): Unit

Clears the cache by removing all entries.
abstract def get(key: Any): 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.
abstract def keys: Set[Any]

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).
abstract def remove(key: Any): Option[Future[V]]

Removes the cache item for the given key.
Removes the cache item for the given key. Returns the removed item if it was found (and removed).
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).
