Interface WorkQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
WorkSearchSession
public interface WorkQuerySession extends OsidSession

This session provides methods for searching among Work objects. The search query is constructed using the WorkQuery.

This session defines views that offer differing behaviors for searching.

  • federated foundry view: searches include works in foundries of which this foundry is an ancestor in the foundry hierarchy
  • isolated foundry view: searches are restricted to works in this foundry

Works may have a query record indicated by their respective record types. The query record is accessed via the WorkQuery.

    • getFoundryId

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

    • getFoundry

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

    • canSearchWorks

      boolean canSearchWorks()
      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.

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

    • useFederatedFoundryView

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

    • useIsolatedFoundryView

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

    • getWorkQuery

      WorkQuery getWorkQuery()
      Gets a work query.
      Returns:
      the work query
      Compliance:
      mandatory - This method must be implemented.

    • getWorksByQuery

      WorkList getWorksByQuery(WorkQuery workQuery) throws OperationFailedException, PermissionDeniedException
      Gets a list of Works matching the given work query.
      Parameters:
      workQuery - the work query
      Returns:
      the returned WorkList
      Throws:
      NullArgumentException - workQuery is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      UnsupportedException - workQuery is not of this service
      Compliance:
