All Superinterfaces:

All Known Subinterfaces:

public interface RealmAdminSession
extends OsidSession

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

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

The delete operations delete Realms. It is safer to remove all mappings to the Realm catalogs before deletion.

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

Method Detail

canCreateRealms

boolean canCreateRealms()

Tests if this user can create Realms. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Realm 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 Realm creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateRealmWithRecordTypes

boolean canCreateRealmWithRecordTypes(Type[] realmRecordTypes)

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

Parameters:

realmRecordTypes - array of types

Returns:

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

Throws:

NullArgumentException - realmRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getRealmFormForCreate

RealmForm getRealmFormForCreate(Type[] realmRecordTypes)
                                throws OperationFailedException,
                                       PermissionDeniedException

Gets the realm form for creating new realms. A new form should be requested for each create transaction.

Parameters:

realmRecordTypes - array of types

Returns:

the realm form

Throws:

NullArgumentException - realmRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - cannot get form for requested record types

Compliance:

mandatory - This method must be implemented.

createRealm

Realm createRealm(RealmForm realmForm)
                  throws OperationFailedException,
                         PermissionDeniedException

Creates a new Realm.

Parameters:

realmForm - the form for this Realm

Returns:

the new Realm

Throws:

IllegalStateException - realmForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - realmForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - realmForm did not originate from getRealmFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateRealms

boolean canUpdateRealms()

Tests if this user can update Realms. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a Realm 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 Realm modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getRealmFormForUpdate

RealmForm getRealmFormForUpdate(Id realmId)
                                throws NotFoundException,
                                       OperationFailedException,
                                       PermissionDeniedException

Gets the realm form for updating an existing realm. A new realm form should be requested for each update transaction.

Parameters:
