Interface CheckQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
CheckSearchSession
public interface CheckQuerySession extends OsidSession

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

This session defines views that offer differing behaviors for searching.

  • federated engine view: searches include checks in engines of which this engine is an ancestor in the engine hierarchy
  • isolated engine view: searches are restricted to checks in this engine

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

      mandatory - This method must be implemented.

    • useFederatedEngineView

      void useFederatedEngineView()
      Federates the view for methods in this session. A federated view will include checks in engines which are children of this engine in the engine hierarchy.
      Compliance:
      mandatory - This method is must be implemented.

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

    • getCheckQuery

      CheckQuery getCheckQuery()
      Gets a check query.
      Returns:
      the check query
