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

Interface	osid.calendaring.rules.SupersedingEventEnablerLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `SupersedingEventEnablers.` 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 superseding event enabler methods in this session operate, retrieve and pertain to superseding event enablers defined explicitly in the current calendar. Using an isolated view is useful for managing `SupersedingEventEnablers` with the `SupersedingEventEnablerAdminSession.` federated calendar view: All superseding event enabler methods in this session operate, retrieve and pertain to all superseding event enablers defined in this calendar and any other superseding event enablers implicitly available in this calendar through calendar inheritence. active superseding event enabler view: All superseding event enabler lookup methods return active superseding event enablers. any status superseding event enabler view: superseding event enablers of any active or 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

Compliance	`mandatory`		This method must be implemented.
Method	useComparativeSupersedingEventEnablerView
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	usePlenarySupersedingEventEnablerView
Description	A complete view of the `SupersedingEventEnabler` 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.
