Interface ControllerQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
ControllerSearchSession
public interface ControllerQuerySession extends OsidSession

This session provides methods for searching among Controllers . The search query is constructed using the ControllerQuery .

This session defines views that offer differing behaviors for searching.

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

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