Interface CalendarAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

CalendarBatchAdminSession

public interface CalendarAdminSession
extends OsidSession

This session creates, updates, and deletes Calendars. The data for create and update is provided by the consumer via the form object. OsidForms are requested for each create or update and may not be reused.

Create and update operations differ in their usage. To create a Calendar, a CalendarForm is requested using getCalendarFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned CalendarForm will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the CalendarForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each CalendarForm corresponds to an attempted transaction.

For updates, CalendarForms are requested to the Calendar Id that is to be updated using getCalendarFormForUpdate(). Similarly, the CalendarForm has metadata about the data that can be updated and it can perform validation before submitting the update. The Calendar can only be used once for a successful update and cannot be reused.

The delete operations delete Calendars. This session also includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.

Method Detail

canCreateCalendars

boolean canCreateCalendars()

Tests if this user can create Calendars. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Calendar will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer create operations to unauthorized users.

Returns:

false if Calendar creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateCalendarWithRecordTypes

boolean canCreateCalendarWithRecordTypes(Type[] calendarRecordTypes)

Tests if this user can create a single Calendar using the desired record types. While CalendaringManager.getCalendarRecordTypes() can be used to examine which records are supported, this method tests which record(s) are required for creating a specific Calendar. Providing an empty array tests if a Calendar can be created with no records.

Parameters:

calendarRecordTypes - array of calendar record types

Returns:

true if Calendar creation using the specified Types is supported, false otherwise

Throws:

NullArgumentException - calendarRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getCalendarFormForCreate

CalendarForm getCalendarFormForCreate(Type[] calendarRecordTypes)
                                      throws OperationFailedException,
                                             PermissionDeniedException

the calendar form

Throws:

NullArgumentException - calendarRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

createCalendar

CalendarForm createCalendar(CalendarForm calendarForm)
                            throws OperationFailedException,

Parameters:

calendarForm - the form for this Calendar

Returns:

the new Calendar

Throws:

IllegalStateException - calendarForm already used for a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - calendarForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - calendarForm did not originate from getCalendarFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateCalendars

boolean canUpdateCalendars()

Tests if this user can update Calendars. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a Calendar will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer update operations to unauthorized users.

Returns:

false if Calendar modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getCalendarFormForUpdate

CalendarForm getCalendarFormForUpdate(Id calendarId)
                                      throws NotFoundException,
