Type Members

1. class AlgebraicMutableCache[K, V] extends AnyRef

2. class AlgebraicReadableStore[K, V] extends AnyRef

3. class AlgebraicStore[K, V] extends AnyRef

4. class BufferingMergeable[K, V] extends Mergeable[K, V]

   A Mergeable that sits on top of another mergeable and pre-aggregates before pushing into merge/multiMerge This is very useful for cases where you have some keys that are very hot, or you have a remote mergeable that you don't want to constantly hit.

5. class BufferingStore[K, V] extends BufferingMergeable[K, V] with MergeableStore[K, V]

   A MergeableStore that does the same buffering as BufferingMergeable, but flushes on put/get.

6. class ConvertedMergeableStore[K1, -K2, V1, V2] extends storehaus.ConvertedStore[K1, K2, V1, V2] with MergeableStore[K2, V2]

   Caveat Emptor! The semigroup on the resulting ConvertedMergeableStore will be the bijected semigroup from Semigroup[V1] => Semigroup[V2].

7. class EnrichedMergeableStore[K, V] extends AnyRef

   Enrichment on the com.twitter.storehaus.algebra.MergeableStore trait.

8. case class ExpiredException[K, V](pair: (K, V)) extends RuntimeException with Product with Serializable

   Injection that maps values paired with stale values of T => None on inversion.

9. trait Mergeable[-K, V] extends Closable

   Main trait to represent objects that are used for aggregation

10. class MergeableJMapLongStore[K] extends MergeableJMapStore[K, Long]

    MergeableStore instance that is backed by a ConcurrentHashMap This class is thread safe with a locking merge operation and thread safe put/get operations provided by the underlying ConcurrentHashMap There is no multi operation optimization so all multi operations use the default Store implementation.

11. class MergeableJMapStore[K, V] extends MergeableStore[K, V]

12. class MergeableMonoidStore[-K, V] extends MergeableStoreViaGetPut[K, V]

    Uses the monoid and filters zeros on put.

13. trait MergeableProxy[K, V] extends Mergeable[K, V] with Proxied[Mergeable[K, V]]

    Proxy for Mergeables.

14. trait MergeableStore[-K, V] extends Store[K, V] with Mergeable[K, V]

    Main trait to represent stores that are used for aggregation

15. trait MergeableStoreProxy[K, V] extends MergeableStore[K, V] with Proxied[MergeableStore[K, V]]

    Proxy for MergeableStoress.

16. class MergeableStoreViaGetPut[-K, V] extends MergeableStoreViaSingleGetPut[K, V]

17. class MergeableStoreViaSingleGetPut[-K, V] extends MergeableStore[K, V]

    Just get, locally merge, then put.

18. case class PromiseLink[V](promise: Promise[Option[V]], value: V) extends Product with Serializable

    This class allows code to depends on the data that a value will be combined with, fulfilling the Promise with the value just before the value is added in.

19. class PromiseLinkMonoid[V] extends PromiseLinkSemigroup[V] with Monoid[PromiseLink[V]]

    TODO: REMOVE WHEN NEXT VERSION OF ALGEBIRD IS PUBLISHED https://github.

20. class PromiseLinkSemigroup[V] extends Semigroup[PromiseLink[V]]

21. class ReadableStoreMonoid[K, V] extends ReadableStoreSemigroup[K, V] with Monoid[ReadableStore[K, V]]

    Same as a ReadableStoreSemigroup except with a zero that the constant store always returning Monoid.

22. class ReadableStoreSemigroup[K, V] extends Semigroup[ReadableStore[K, V]]

    A semigroup that uses the future semigroup to add results of both gets

23. trait SummerConstructor[K] extends AnyRef

    For any given V, construct a StatefulSummer of Map[K, V]

24. class TTLInjection[K, T, V] extends Injection[(K, V), (K, (T, V))]

25. class UnpivotedMergeableStore[-K, OuterK, InnerK, V] extends UnpivotedStore[K, OuterK, InnerK, V] with MergeableStore[K, V]

    MergeableStore enrichment which presents a MergeableStore[K, V] over top of a packed MergeableStore[OuterK, Map[InnerK, V]].

26. class ConvertedStore[K1, -K2, V1, V2] extends ConvertedReadableStore[K1, K2, V1, V2] with Store[K2, V2]

    Use an injection on V2,V1 to convert a store of values V2.
