public interface ActionEnablerQuerySession extends OsidSession

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

This session defines views that offer differing behaviors for searching.

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

Action constrainer enablers may have a query record indicated by their respective record types. The query record is accessed via the ActionEnablerQuery .
