Interface SceneLookupSession

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

This session defines methods for retrieving scenes.

This lookup session defines several views:

  • comparative view: elements may be silently omitted or re-ordered
  • plenary view: provides a complete result set or is an error condition
  • isolated system view: All scene methods in this session operate, retrieve and pertain to scenes defined explicitly in the current system. Using an isolated view is useful for managing Scenes with the SceneAdminSession .
  • federated system view: All scene lookup methods in this session operate, retrieve and pertain to all scenes defined in this system and any other scenes implicitly available in this system through system inheritence.

The methods useFederatedSystemView() and useIsolatedSystemView() behave as a radio group and one should be selected before invoking any lookup methods.

Scenes may have an additional records indicated by their respective record types. The record may not be accessed through a cast of the scenes.

  • Method Details

    • getSystemId

      Id getSystemId()
      Gets the System Id associated with this session.
      Returns:
      the System Id associated with this session
      Compliance:
      mandatory - This method must be implemented.

    • getSystem

      System getSystem() throws OperationFailedException, PermissionDeniedException
      Gets the System associated with this session.
      Returns:
      the system
      Throws:
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      Compliance:
      mandatory - This method must be implemented.

    • canLookupScenes

      boolean canLookupScenes()
      Tests if this user can perform Scene 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 not offer lookup operations to unauthorized users.
      Returns:
      false if lookup methods are not authorized, true otherwise
      Compliance:
      mandatory - This method must be implemented.

    • useComparativeSceneView

      void useComparativeSceneView()
      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.

    • usePlenarySceneView

      void usePlenarySceneView()
      A complete view of the Scene 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.

    • useFederatedSystemView

      void useFederatedSystemView()
      Federates the view for methods in this session. A federated view will include scenes in systems which are children of this system in the system hierarchy.
      Compliance:
      mandatory - This method is must be implemented.

    • useIsolatedSystemView

      void useIsolatedSystemView()
      Isolates the view for methods in this session. An isolated view restricts retrievals to this system only.
      Compliance:
      mandatory - This method is must be implemented.

    • getScene

      Scene getScene(Id sceneId) throws NotFoundException, OperationFailedException, PermissionDeniedException

      sceneId - the Id of the Scene to retrieve
      Returns:

      NullArgumentException - sceneId is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      Compliance:
      mandatory - This method must be implemented.

    • getScenesByIds

      SceneList getScenesByIds(IdList sceneIds) throws NotFoundException, OperationFailedException, PermissionDeniedException
      Gets a SceneList corresponding to the given IdList . In plenary mode, the returned list contains all of the scenes specified in the Id list, in the order of the list, including duplicates, or an error results if an Id in the supplied list is not found or inaccessible. Otherwise, inaccessible Scenes may be omitted from the list and may present the elements in any order including returning a unique set.
      Parameters:
      sceneIds - the list of Ids to retrieve
