public interface DictionaryAdminSession
extends OsidSession

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

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

The delete operations delete Dictionaries.

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

Method Detail

canCreateDictionaries

boolean canCreateDictionaries()

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

Returns:

false if Dictionary creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateDictionaryWithRecordTypes

boolean canCreateDictionaryWithRecordTypes(Type[] dictionaryRecordTypes)

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

Parameters:

dictionaryRecordTypes - array of dictionary record types

Returns:

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

Throws:

NullArgumentException - dictionaryRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getDictionaryFormForCreate

DictionaryForm getDictionaryFormForCreate(Type[] dictionaryRecordTypes)
                                          throws OperationFailedException,
                                                 PermissionDeniedException

Gets the dictionary form for creating new dictionaries. A new form should be requested for each create transaction.

Parameters:

dictionaryRecordTypes - array of dictionary record types

Returns:

the dictionary form

Throws:

NullArgumentException - dictionaryRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.

createDictionary

Dictionary createDictionary(DictionaryForm dictionaryForm)
                            throws OperationFailedException,
                                   PermissionDeniedException

Creates a new Dictionary.

Parameters:

dictionaryForm - the form for the new Dictionary

Returns:

the new Dictionary

Throws:

IllegalStateException - dictionaryForm already used in a create transaction

InvalidArgumentException - the form contains an invalid value

NullArgumentException - dictionaryForms is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - dictionaryForm did not originate from getDictionaryFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateDictionaries

boolean canUpdateDictionaries()

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

Returns:

false if Dictionary modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getDictionaryFormForUpdate

DictionaryForm getDictionaryFormForUpdate(Id dictionaryId)
                                          throws NotFoundException,
                                                 OperationFailedException,
                                                 PermissionDeniedException

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

Parameters:

dictionaryId - the Id of the Dictionary

Returns:

the dictionary form

Throws:

NotFoundException - dictionaryId is not found

NullArgumentException - dictionaryId is null

OperationFailedException - unable to complete request
