All Superinterfaces:

All Known Subinterfaces:

public interface RepositoryAdminSession
extends OsidSession

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

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

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

Method Detail

canCreateRepositories

boolean canCreateRepositories()

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

Compliance:

mandatory - This method must be implemented.

canCreateRepositoryWithRecordTypes

boolean canCreateRepositoryWithRecordTypes(Type[] repositoryRecordTypes)

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

Parameters:

repositoryRecordTypes - array of repository record types

Returns:

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

Throws:

NullArgumentException - repositoryRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getRepositoryFormForCreate

RepositoryForm getRepositoryFormForCreate(Type[] repositoryRecordTypes)
                                          throws OperationFailedException,
                                                 PermissionDeniedException

Gets the repository form for creating new repositories. A new form should be requested for each create transaction.

Parameters:

repositoryRecordTypes - array of repository record types

Returns:

the repository form

Throws:

NullArgumentException - repositoryRecordTypes 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.

createRepository

Repository createRepository(RepositoryForm repositoryForm)
                            throws OperationFailedException,
                                   PermissionDeniedException

Creates a new Repository.

Parameters:

repositoryForm - the form for this Repository

Returns:

the new Repository

Throws:

IllegalStateException - repositoryForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - repositoryForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - repositoryForm did not originate from getRepositoryFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateRepositories

boolean canUpdateRepositories()

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

Compliance:

mandatory - This method must be implemented.

getRepositoryFormForUpdate

RepositoryForm getRepositoryFormForUpdate(Id repositoryId)
                                          throws NotFoundException,
                                                 OperationFailedException,
                                                 PermissionDeniedException

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

Parameters:

repositoryId - the Id of the Repository

Returns:

the repository form

Throws:

NotFoundException - repositoryId is not found

NullArgumentException - repositoryId is null

OperationFailedException - unable to complete request
