com.couchbase.mock.memcached.Storage

public class Storage
extends Object

Class representing a node's storage. This has both a "cache" and a "persistent" store, with the aim to support full replication and persistence semantics. The "cache" store receives items (either via a set or a delete). Once this is done, the replication and/or persistence hooks are invoked. The persistent store keeps a copy of each Item (when persisted), and each server's "Replica" keeps a new copy of the same Item as well. While this is probably not the most efficient way to go about things, it is crucial in order to be able to test these types of semantics.
