- abstract def cacheContains(key: K, tx: T)(implicit path: T.Acc): Boolean
- abstract def flushCache(term: Long)(implicit tx: T): Unit
This method should be invoked from the implementations flush hook after it has determined the terminal version at which the entries in the cache are written to the persistent store.
This method should be invoked from the implementations flush hook after it has determined the terminal version at which the entries in the cache are written to the persistent store. If this method is not called, the cache will just vanish and not be written out to the
persistentstore.- term
the new version to append to the paths in the cache (using the
PathLike'saddTermmethod)- tx
the current transaction (should be in commit or right-before commit phase)
- abstract def getCacheOnly[A](key: K, tx: T)(implicit path: T.Acc): Option[A]
- abstract def removeCache(key: K, tx: T)(implicit path: T.Acc): Boolean
- abstract def removeCacheOnly(key: K, tx: T)(implicit path: T.Acc): Boolean
Removes an entry from the cache, and only the cache.
Removes an entry from the cache, and only the cache. This will not affect any values also persisted to
persistent! If the cache does not contain an entry at the givenkey, this method simply returns.- key
key at which the entry is stored
- tx
the current transaction
- abstract def store: Store
The persistent map to which the data is flushed or from which it is retrieved when not residing in cache.
