Interface QueueAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

QueueBatchAdminSession

public interface QueueAdminSession
extends OsidSession

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

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

The delete operations delete Queues. To unmap a Queue from the current Distributor, the QueueDistributorAssignmentSession should be used. These delete operations attempt to remove the Queue itself thus removing it from all known Distributor catalogs.

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

Method Detail

getDistributorId

Id getDistributorId()

Gets the Distributor Id associated with this session.

Returns:

the Distributor Id associated with this session

Compliance:

mandatory - This method must be implemented.

getDistributor

Distributor getDistributor()
                           throws OperationFailedException,
                                  PermissionDeniedException

Gets the Distributor associated with this session.

Returns:

the distributor

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateQueue

boolean canCreateQueue()

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

Compliance:

mandatory - This method must be implemented.

canCreateQueueWithRecordTypes

boolean canCreateQueueWithRecordTypes(Type[] queueRecordTypes)

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

Parameters:

queueRecordTypes - array of queue record types

Returns:

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

Throws:

NullArgumentException - queueRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getQueueFormForCreate

QueueForm getQueueFormForCreate(Id brokerId,
                              Type[] queueRecordTypes)
                                throws NotFoundException,
                                       OperationFailedException,
                                       PermissionDeniedException

Gets the queue form for creating new queues. A new form should be requested for each create transaction.

Parameters:

brokerId - a broker Id

queueRecordTypes - array of queue record types

Returns:

the queue form

Throws:

NotFoundException - brokerId is not found

NullArgumentException - brokerId or queueRecordTypes 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.

createQueue

Queue createQueue(QueueForm queueForm)
                  throws OperationFailedException,
                         PermissionDeniedException

Creates a new Queue.

Parameters:

queueForm - the form for this Queue

Returns:

the new Queue

Throws:

IllegalStateException - queueForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - queueForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - queueForm did not originate from getQueueFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateQueues

boolean canUpdateQueues()

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

Compliance:

mandatory - This method must be implemented.
