public class InMemoryObjectStore
- extends AbstractMonitoredObjectStore
InMemoryObjectStore
implements an optionally bounded
in-memory store for message IDs with periodic expiry of old entries. The bounded size
is a soft limit and only enforced periodically by the expiry process; this
means that the store may temporarily exceed its maximum size between expiry runs, but
will eventually shrink to its configured size.DO
