OSID - osid.calendaring.rules.RecurringEventEnablerLookupSession Service Interface Definition

Interface	osid.calendaring.rules.RecurringEventEnablerLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `RecurringEventEnablers.` 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 enabler methods in this session operate, retrieve and pertain to recurring event enablers defined explicitly in the current calendar. Using an isolated view is useful for managing `RecurringEventEnablers` with the `RecurringEventEnablerAdminSession.` federated calendar view: All recurring event enabler methods in this session operate, retrieve and pertain to all recurring event enablers defined in this calendar and any other recurring event enablers implicitly available in this calendar through calendar inheritence. active recurring event enabler view: All recurring event enabler lookup methods return active offset event enablers. any status recurring event enabler view: Recurring event enablers of any active and inactive status are returned from methods. 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 `useFederatedDistributorView()` and `useIsolatedDistributorView()` behave as a radio group and one should be selected before invoking the methods in this session.
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
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupRecurringEventEnablers
Description	Tests if this user can perform `RecurringEventEnabler` 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	useComparativeRecurringEventEnablerView
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	usePlenaryRecurringEventEnablerView
Description	A complete view of the `RecurringEventEnabler` 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 event enablers 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	useActiveRecurringEventEnablerView
Description	Only active recurring event enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useAnyStatusRecurringEventEnablerView
Description	All active and inactive recurring event enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	getRecurringEventEnabler
