Interface CourseQuerySession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

All Known Subinterfaces:

CourseSearchSession

public interface CourseQuerySession
extends OsidSession

This session provides methods for searching among Courses . The search query is constructed using the CourseQuery .

This session defines views that offer differing behaviors for searching.

• federated course catalog view: searches include courses in course catalogs of which this course catalog is an ancestor in the course catalog hierarchy
• isolated course catalog view: searches are restricted to courses in this course catalog

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