Detailed Description

The NoOpJournalListener is a trivial implementation of a JournalListener, that does nothing.

NoOpJournalListener::instance exists simply as a default implementation for storage engines to use until they are passed a JournalListener with greater functionality, allowing us to avoid checking for JournalListener-nullness.
