Interface CourseEntryQuerySession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

All Known Subinterfaces:

CourseEntrySearchSession

public interface CourseEntryQuerySession
extends OsidSession

This session provides methods for searching among CourseEntries. The search query is constructed using the CourseEntryQuery.

This session defines views that offer differing behaviors for searching.

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

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

canSearchCourseEntries

boolean canSearchCourseEntries()

Tests if this user can perform CourseEntry searches. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer search operations to unauthorized users.

Returns:

false if search methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useFederatedCourseCatalogView

void useFederatedCourseCatalogView()

Compliance:

mandatory - This method is must be implemented.

useIsolatedCourseCatalogView

void useIsolatedCourseCatalogView()

Isolates the view for methods in this session. An isolated view restricts lookups to this course catalog only.

Compliance:

mandatory - This method is must be implemented.

Returns:

the course entry query

Compliance:

mandatory - This method must be implemented.

getCourseEntriesByQuery
