Interface TriggerQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
TriggerSearchSession
public interface TriggerQuerySession extends OsidSession

This session provides methods for searching among Triggers. The search query is constructed using the TriggerQuery.

This session defines views that offer differing behaviors for searching.

  • federated system view: searches include triggers in systems of which this system is an ancestor in the system hierarchy
  • isolated system view: searches are restricted to triggers in this system

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

    • useFederatedSystemView

      void useFederatedSystemView()
      Federates the view for methods in this session. A federated view will include triggers 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 searches to this system only.
      Compliance:
