Interface WorkNotificationSession

All Superinterfaces:

public interface WorkNotificationSession
extends OsidSession

This session defines methods to receive notifications on adds/changes to Work objects in this Foundry. This also includes existing works that may appear or disappear due to changes in the Foundry hierarchy, 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.

The two views defined in this session correspond to the views in the WorkLookupSession.
