Interface RuleNotificationSession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession

public interface RuleNotificationSession extends OsidSession

This session defines methods to receive notifications on adds/changes to Rules. This session is intended for consumers needing to synchronize their state with this service without the use of polling. Notifications are cancelled when this session is closed.

Like all OsidSessions, RuleNotificationSessions are dedicated to single processing threads and a single authenticated user.
