Class DatabaseAvailability

  org.neo4j.kernel.DatabaseAvailability

All Implemented Interfaces:

Lifecycle

public class DatabaseAvailability
extends Object
implements Lifecycle

This class handles whether the database as a whole is available to use at all. As it runs as the last service in the lifecycle list, the stop() is called first on stop, shutdown or restart, and thus blocks access to everything else for outsiders.
