Interface ActivityQuerySession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

All Known Subinterfaces:

ActivitySearchSession

public interface ActivityQuerySession
extends OsidSession

This session provides methods for searching among Activities . The search query is constructed using the ActivityQuery .

This session defines views that offer differing behaviors for searching.

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

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

Returns:

the course catalog

canSearchActivities

boolean canSearchActivities()

Tests if this user can perform Activity lookups. 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 not offer lookup 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.

getActivityQuery

ActivityQuery getActivityQuery()

Gets an activity query.

Returns:

the activity query

Compliance:

mandatory - This method must be implemented.

getActivitiesByQuery
