Interface QueueLookupSession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
public interface QueueLookupSession extends OsidSession

This session provides methods for retrieving Queue objects. The Queue represents a fixed connection between two Issues .

This session defines views that offer differing behaviors when retrieving multiple objects.

  • comparative view: elements may be silently omitted or re-ordered
  • plenary view: provides a complete set or is an error condition
  • isolated front office view: All queue methods in this session operate, retrieve and pertain to queues defined explicitly in the current front office. Using an isolated view is useful for managing Queues with the QueueAdminSession .
  • federated front office view: All queue methods in this session operate, retrieve and pertain to all queues defined in this front office and any other queues implicitly available in this front office through front office inheritence.
  • active queue view: active queue are returned from methods in this session
  • any status queue view: active and inactive queues are returned from methods in this session

Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods useFederatedFrontOfficeView() and useIsolatedFrontOfficeView() behave as a radio group and one should be selected before invoking any lookup methods.

      mandatory - This method must be implemented.

    • canLookupQueues

      boolean canLookupQueues()
      Tests if this user can perform Queue lookups. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a PERMISSION_DENIED . This is intended as a hint to an application that may opt not to offer lookup operations to unauthorized users.

      false if lookup methods are not authorized, true otherwise
      Compliance:
      mandatory - This method must be implemented.

    • useComparativeQueueView

      void useComparativeQueueView()
      The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
      Compliance:
      mandatory - This method is must be implemented.

    • usePlenaryQueueView

      void usePlenaryQueueView()
      A complete view of the Queue returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.
      Compliance:
      mandatory - This method is must be implemented.

    • useFederatedFrontOfficeView

      mandatory - This method is must be implemented.

    • useIsolatedFrontOfficeView

      void useIsolatedFrontOfficeView()
