  8. def get(key: K): Future[V]

    Returns the future associated with key in this cache, obtaining that value from loader if necessary.

    Returns the future associated with key in this cache, obtaining that value from loader if necessary. If the asynchronous computation fails, the entry will be automatically removed.

    key

    key with which the specified value is to be associated

    returns

    the current (existing or computed) future value associated with the specified key

    Exceptions thrown

    java.lang.RuntimeException or Error if the loader does when constructing the future, in which case the mapping is left unestablished

  9. def get(key: K, mappingFunction: (K) => V): Future[V]

    Returns the future associated with key in this cache, obtaining that value from mappingFunction if necessary.

    Returns the future associated with key in this cache, obtaining that value from mappingFunction if necessary. This method provides a simple substitute for the conventional "if cached, return; otherwise create, cache and return" pattern.

    key

    key with which the specified value is to be associated

    mappingFunction

    the function to asynchronously compute a value

    returns

    the current (existing or computed) future value associated with the specified key

    Definition Classes
    AsyncCache
  10. def getAll(keys: Iterable[K]): Future[Map[K, V]]

    Returns the future of a map of the values associated with keys, creating or retrieving those values if necessary.

    Returns the future of a map of the values associated with keys, creating or retrieving those values if necessary. The returned map contains entries that were already cached, combined with newly loaded entries. If the any of the asynchronous computations fail, those entries will be automatically removed.

    keys

    the keys whose associated values are to be returned

    returns

    the future containing an mapping of keys to values for the specified keys in this cache

    Exceptions thrown

    java.lang.RuntimeException or Error if the loader does so

  11. def getAll(keys: Iterable[K], mappingFunction: (Iterable[K]) => Map[K, V]): Future[Map[K, V]]

    Returns the future of a map of the values associated with keys, creating or retrieving those values if necessary.

    Returns the future of a map of the values associated with keys, creating or retrieving those values if necessary. The returned map contains entries that were already cached, combined with newly loaded entries. If the any of the asynchronous computations fail, those entries will be automatically removed from this cache.

    A single request to the mappingFunction is performed for all keys which are not already present in the cache.

    keys

    the keys whose associated values are to be returned

    mappingFunction

    the function to asynchronously compute the values

    returns

    the future containing an unmodifiable mapping of keys to values for the specified keys in this cache

    Definition Classes
    AsyncCache
    Exceptions thrown

    java.lang.RuntimeException or Error if the mappingFunction does when constructing the future, in which case the mapping is left unestablished

  12. def getAllFuture(keys: Iterable[K], mappingFunction: (Iterable[K]) => Future[Map[K, V]]): Future[Map[K, V]]

    Returns the future of a map of the values associated with keys, creating or retrieving those values if necessary.

    Returns the future of a map of the values associated with keys, creating or retrieving those values if necessary. The returned map contains entries that were already cached, combined with newly loaded entries. If the any of the asynchronous computations fail, those entries will be automatically removed from this cache.

    Returns the future associated with key in this cache, obtaining that value from mappingFunction if necessary. This method provides a simple substitute for the conventional "if cached, return; otherwise create, cache and return" pattern.

    key

    key with which the specified value is to be associated

  15. def getIfPresent(key: K): Option[Future[V]]

    Returns the future associated with key in this cache, or None if there is no cached future for key.

    Returns the future associated with key in this cache, or None if there is no cached future for key.

    key

    key whose associated value is to be returned

    returns

    an option containing the current (existing or computed) future value to which the specified key is mapped, or None if this map contains no mapping for the key

    Associates value with key in this cache.

    Associates value with key in this cache. If the cache previously contained a value associated with key, the old value is replaced by value. If the asynchronous computation fails, the entry will be automatically removed.

    key

    key with which the specified value is to be associated

  23. def synchronous(): LoadingCache[K, V]

    Returns a view of the entries stored in this cache as a synchronous LoadingCache.

    Returns a view of the entries stored in this cache as a synchronous LoadingCache. A mapping is not present if the value is currently being loaded. Modifications made to the synchronous cache directly affect the asynchronous cache. If a modification is made to a mapping that is currently loading, the operation blocks until the computation completes.

    returns

    a thread-safe synchronous view of this cache
