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.
