OSID - osid.course.ActivityLookupSession Service Interface Definition

Interface	osid.course.ActivityLookupSession
Implements	`osid.OsidSession`
Used By	`osid.course.CourseManager`
Used By	`osid.course.CourseProxyManager`
Description	This session provides methods for retrieving `Activities`. The `Activity` represents a time period in which courses are offered. This session defines views that offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete set or is an error condition isolated course catalog view: All activity methods in this session operate, retrieve and pertain to activities defined explicitly in the current course catalog. Using an isolated view is useful for managing `Activities` with the `ActivityAdminSession`. federated course catalog view: All activity methods in this session operate, retrieve and pertain to all activities defined in this course catalog and any other activities implicitly available in this course catalog through course catalog inheritence. effective activity view: All course offering lookup methods return activities where the current date falls within the effective dates inclusive. any effective activity view: Activities of any effective or expired status are returned from methods. denormalized activity view: activities are expanded into a series of non-recurring single-date activities normalized acticity view: activities are represented by a single activity Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods `useFederatedCourseCatalogView()` and `useIsolatedCourseCatalogView()` behave as a radio group and one should be selected before invoking any lookup methods.
Method	getCourseCatalogId
Description	Gets the `CourseCatalog` `Id` associated with this session.
Return	`osid.id.Id`		the `CourseCatalog Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getCourseCatalog
Description	Gets the `CourseCatalog` associated with this session.
Return	`osid.course.CourseCatalog`		the course catalog
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure

Method	canLookupActivities
Description	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 opt not to offer lookup operations to unauthorized users.
Return	`boolean`		`false` if lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeActivityView
Description	The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
Compliance	`mandatory`		This method is must be implemented.
Method	usePlenaryActivityView
Description	A complete view of the `Activity` returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.
Compliance	`mandatory`		This method is must be implemented.
Method	useFederatedCourseCatalogView
Description	Federates the view for methods in this session. A federated view will include activities in course catalogs which are children of this course catalog in the course catalog hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedCourseCatalogView
Description	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.
Method	useAnyEffectiveActivityView

Compliance	`mandatory`		This method is must be implemented.
Method	useNormalizedActivityView
Description	A normalized view uses a single `Activity` to represent a set of recurring activities.

Method	useDenormalizedActivityView
Description	A denormalized view expands recurring activities into a series of activities.
Compliance	`mandatory`		This method is must be implemented.
