Interface WorkLookupSession

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

This session provides methods for retrieving Works . The Work represents a fixed connection between two Availabilities .

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 office view: All work methods in this session operate, retrieve and pertain to works defined explicitly in the current office. Using an isolated view is useful for managing Works with the WorkAdminSession .
  • federated office view: All work methods in this session operate, retrieve and pertain to all works defined in this office and any other works implicitly available in this office through office inheritence.

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 useFederatedOfficeView() and useIsolatedOfficeView() behave as a radio group and one should be selected before invoking any lookup methods.

    • getOfficeId

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

    • getOffice

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

    • canLookupWorks

      boolean canLookupWorks()
      Tests if this user can perform Work 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.
      Returns:
      false if lookup methods are not authorized, true otherwise
      Compliance:
      mandatory - This method must be implemented.

    • useComparativeWorkView

      void useComparativeWorkView()
      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.

    • usePlenaryWorkView

      void usePlenaryWorkView()
      A complete view of the Work 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.

    • useFederatedOfficeView

      void useFederatedOfficeView()
      Federates the view for methods in this session. A federated view will include works in offices which are children of this office in the office hierarchy.
      Compliance:
      mandatory - This method is must be implemented.

    • useIsolatedOfficeView

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

    • getWork

      Work getWork(Id workId) throws NotFoundException, OperationFailedException, PermissionDeniedException
      Gets the Work specified by its Id . In plenary mode, the exact Id is found or a NOT_FOUND results. Otherwise, the returned Work may have a different Id than requested, such as the case where a duplicate Id was assigned to a Work and retained for compatibility.
      Parameters:
      workId - Id of the Work
      Returns:
      the work
      Throws:
      NotFoundException - workId not found
      NullArgumentException - workId is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      Compliance:
      mandatory - This method is must be implemented.

    • getWorksByIds

      WorkList getWorksByIds(IdList workIds) throws NotFoundException, OperationFailedException, PermissionDeniedException
      Gets a WorkList corresponding to the given IdList . In plenary mode, the returned list contains all of the works 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 Works may be omitted from the list and may present the elements in any order including returning a unique set.
      Parameters:
      workIds - the list of Ids to retrieve
      Returns:
      the returned Work list
      Throws:
      NotFoundException - an Id was not found
      NullArgumentException - workIds is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure

      mandatory - This method must be implemented.

    • getWorksByGenusType

      WorkList getWorksByGenusType(Type workGenusType) throws OperationFailedException, PermissionDeniedException

In plenary mode, the returned list contains all known works or an error results. Otherwise, the returned list may contain only those works that are accessible through this session.
      Parameters:
      workGenusType - a work genus type

      the returned Work list
      Throws:
      NullArgumentException - workGenusType is null
      OperationFailedException - unable to complete request
