Interface QueueProcessorNotificationSession

All Superinterfaces:

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

public interface QueueProcessorNotificationSession
extends OsidSession

This session defines methods to receive notifications on adds/changes to QueueProcessor objects in this Distributor. This also includes existing QueueProcessors that may appear or disappear due to changes in the Distributor hierarchy, This session is intended for consumers needing to synchronize their state with this service without the use of polling. Notifications are cancelled when this session is closed.

The two views defined in this session correspond to the views in the QueueProcessorLookupSession.

canRegisterForQueueProcessorNotifications

boolean canRegisterForQueueProcessorNotifications()

Tests if this user can register for QueueProcessor notifications. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer notification operations.

Returns:

false if notification methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useFederatedDistributorView

void useFederatedDistributorView()

Federates the view for methods in this session. A federated view will include in distributors which are children of this distributor in the distributor hierarchy.

Compliance:

mandatory - This method is must be implemented.

useIsolatedDistributorView

void useIsolatedDistributorView()

Isolates the view for methods in this session. An isolated view restricts notifications to this distributor only.

Compliance:

mandatory - This method is must be implemented.

registerForNewQueueProcessors

void registerForNewQueueProcessors()
                                   throws OperationFailedException,

Register for notifications of new queue processors. QueueProcessorReceiver.newQueueProcessor() is invoked when a new QueueProcessor appears in this distributor.

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

registerForChangedQueueProcessors

void registerForChangedQueueProcessors()
                                       throws OperationFailedException,

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

registerForChangedQueueProcessor

void registerForChangedQueueProcessor(Id queueProcessorId)
                                      throws OperationFailedException,
