OSID - osid.calendaring.RecurringEventLookupSession Service Interface Definition

Interface	osid.calendaring.RecurringEventLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `RecurringEvent` s. 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 calendar view: All recurring event methods in this session operate, retrieve and pertain to events defined explicitly in the current calendar. Using an isolated view is useful for managing recurring events with the `RecurringEventAdminSession.` federated calendar view: All recurring event methods in this session operate, retrieve and pertain to all recurring events defined in this calendar and any other calendars implicitly available in this calendar through calendar inheritence. active recurring event view: All recurring event lookup methods return active recurring events. any status recurring event view: Recurring events of any active or inactive status are returned from methods. sequestered recurring event viiew: All event methods suppress sequestered recurring events. unsequestered recurring event view: All event methods return all recurring events. Events may have an additional records indicated by their respective record types. The record may not be accessed through a cast of the `Event.`
Method	getCalendarId
Description	Gets the `Calendar` `Id` associated with this session.
Return	`osid.id.Id`		the `Calendar Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getCalendar
Description	Gets the `Calendar` associated with this session.
Return	`osid.calendaring.Calendar`		the `Calendar` associated with this session
Errors	OPERATION_FAILED		unable to complete request

Method	canLookupRecurringEvents
Description	Tests if this user can perform `RecurringEvent` 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	useComparativeRecurringEventView
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	usePlenaryRecurringEventView
Description	A complete view of the `Event` 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	useFederatedCalendarView
Description	Federates the view for methods in this session. A federated view will include recurring events in calendars which are children of this calendar in the calendar hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedCalendarView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this calendar only.
Compliance	`mandatory`		This method is must be implemented.
Method	useActiveRecurringEventView
Description	Only active recurring events are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useAnyStatusRecurringEventView
Description	All active and inactive recurring events are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useSequesteredRecurringEventView
Description	The returns from the lookup methods omit sequestered recurring events.
Compliance	`mandatory`		This method is must be implemented.
Method	useUnsequesteredRecurringEventView
Description	All recurring events are returned including sequestered recurring events.
Compliance	`mandatory`		This method is must be implemented.
Method	getRecurringEvent
Description	Gets the `RecurringEvent` specified by its `Id.` In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `RecurringEvent` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to an `Event` and retained for compatibility. In active mode, recurring events are returned that are currently active. In any status mode, active and inactive recurring events are returned.

Method	getRecurringEventsByIds
Description	Gets a `RecurringEventList` corresponding to the given `IdList.` In plenary mode, the returned list contains all of the recurring events specified in the `Id` list, in the order of the list, including duplicates, or an error results if an `Id` in the supplied list is not found or inaccessible. Otherwise, inaccessible `RecurringEvents` may be omitted from the list and may present the elements in any order including returning a unique set. In active mode, recurring events are returned that are currently active. In any status mode, active and inactive recurring events are returned.
