Interface OffsetEventLookupSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

public interface OffsetEventLookupSession
extends OsidSession

This session provides methods for retrieving OffsetEvents.

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 offset event methods in this session operate, retrieve and pertain to offset events defined explicitly in the current calendar. Using an isolated view is useful for managing events with the OffsetEventAdminSession.
• federated calendar view: All offset event methods in this session operate, retrieve and pertain to all offset events defined in this calendar and any other calendars implicitly available in this calendar through calendar inheritence.
• active offset event view: All offset event lookup methods return active offset events.
• any status offset event view: Offset events of any active or inactive status are returned from methods.

Method Detail

getCalendarId

Id getCalendarId()

Gets the Calendar Id associated with this session.

Returns:

the Calendar Id associated with this session

Compliance:

mandatory - This method must be implemented.

getCalendar

Calendar getCalendar()
                     throws OperationFailedException,
                            PermissionDeniedException

Gets the Calendar associated with this session.

Returns:

the Calendar associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canLookupOffsetEvents

boolean canLookupOffsetEvents()

Tests if this user can perform OffsetEvent 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.

Returns:

false if lookup methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useComparativeOffsetEventView

void useComparativeOffsetEventView()

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.

usePlenaryOffsetEventView

void usePlenaryOffsetEventView()

A complete view of the OffsetEvent 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.

useFederatedCalendarView

void useFederatedCalendarView()

Federates the view for methods in this session. A federated view will include offset events in calendars which are children of this calendar in the calendar hierarchy.

Compliance:

mandatory - This method is must be implemented.

useIsolatedCalendarView

void useIsolatedCalendarView()

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.

useActiveOffsetEventView

void useActiveOffsetEventView()

Only active offset events are returned by methods in this session.

Compliance:

mandatory - This method is must be implemented.

useAnyStatusOffsetEventView

void useAnyStatusOffsetEventView()

All active and inactive offset events are returned by methods in this session.

Compliance:

mandatory - This method is must be implemented.

                                  PermissionDeniedException

Gets the OffsetEvent specified by its Id. In plenary mode, the exact Id is found or a NOT_FOUND results. Otherwise, the returned OffsetEvent may have a different Id than requested, such as the case where a duplicate Id was assigned to an OffsetEvent and retained for compatibility. In active mode, offset events are returned that are currently active. In any status mode, active and inactive offset events are returned.

Parameters:

offsetEventId - Id of the OffsetEvent

Returns:

the offset event

Throws:

NotFoundException - offsetEventId not found

Compliance:

mandatory - This method is must be implemented.
