Interface RoomAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

RoomBatchAdminSession

public interface RoomAdminSession
extends OsidSession

This session creates, updates, and deletes Rooms. 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 Room, a RoomForm is requested using getRoomFormForCreate() specifying the desired floor and record Types or none if no record Types are needed. The returned RoomForm 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 RoomForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each RoomForm corresponds to an attempted transaction.

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

The delete operations delete Rooms. To unmap a Room from the current Campus, the RoomCampusAssignmentSession should be used. These delete operations attempt to remove the Room itself thus removing it from all known Campus catalogs.

This session includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.

boolean canCreateRoomWithRecordTypes(Type[] roomRecordTypes)

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

Parameters:

roomRecordTypes - array of room record types

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

NullArgumentException - roomRecordTypes is null

Compliance:

mandatory - This method must be implemented.
