Interface SubjectLookupSession

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

This session provides methods for retrieving Subject s.

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 ontology view: All subject methods in this session operate, retrieve and pertain to subjects defined explicitly in the current ontology. Using an isolated view is useful for managing subjects with the SubjectAdminSession .
  • federated ontology view: All subject methods in this session operate, retrieve and pertain to all subjects defined in this ontology and any other ontologies implicitly available in this ontology through ontology inheritence.

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

    • getOntologyId

      Id getOntologyId()
      Gets the Ontology Id associated with this session.
      Returns:
      the Ontology Id associated with this session

      mandatory - This method must be implemented.

    • canLookupSubjects

      boolean canLookupSubjects()
      Tests if this user can perform Subject 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.

    • useComparativeSubjectView

      void useComparativeSubjectView()
      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.

    • usePlenarySubjectView

      void usePlenarySubjectView()
      A complete view of the Subject 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.

    • useFederatedOntologyView

      void useFederatedOntologyView()
      Federates the view for methods in this session. A federated view will include subjects in ontologies which are children of this ontology in the ontology hierarchy.
      Compliance:
      mandatory - This method is must be implemented.

    • useIsolatedOntologyView

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

    • getSubject
