Interface InternalSession.LockChangeReservation

Enclosing interface:
InternalSession
public static interface InternalSession.LockChangeReservation
Represents a position reserved in this session's lock-change sequence. The reservation captures the notification context when it is created, so completing it later preserves recipient-specific projection and ordering even if the session's views change meanwhile.
