Interface IntersectionNotificationSession
- All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
This session defines methods to receive notifications on adds/changes
to Intersection objects in this Map . This also includes
existing intersections that may appear or disappear due to changes in the
Map 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
IntersectionLookupSession .

Method Details
-
getMapId
Id getMapId()Gets theMapIdassociated with this session.- Returns:
- the
Map Idassociated with this session - Compliance:
mandatory- This method must be implemented.
-
getMap
Gets theMapassociated with this session.- Returns:
- the map
- Throws:
OperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
canRegisterForIntersectionNotifications
boolean canRegisterForIntersectionNotifications()Tests if this user can register forIntersectionnotifications. 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 aPERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer notification operations.- Returns:
falseif notification methods are not authorized,trueotherwise- Compliance:
mandatory- This method must be implemented.
-
useFederatedMapView
void useFederatedMapView()Federates the view for methods in this session. A federated view will include intersections in maps which are children of this map in the map hierarchy.- Compliance:
mandatory- This method is must be implemented.
-
useIsolatedMapView
void useIsolatedMapView()Isolates the view for methods in this session. An isolated view restricts notifications to this map only.- Compliance:
mandatory- This method is must be implemented.
-
acknowledgeIntersectionNotification
void acknowledgeIntersectionNotification(Id notificationId) throws OperationFailedException, PermissionDeniedException Acknowledge a intersection notification.- Parameters:
notificationId- theIdof the notification- Throws:
OperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForNewIntersections
Register for notifications of new intersections.IntersectionReceiver.newIntersections()is invoked when a newIntersectionappears in this map.- Throws:
OperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForNewIntersectionsForPath
void registerForNewIntersectionsForPath(Id pathId) throws OperationFailedException, PermissionDeniedException Register for notifications of new intersections for the given path.IntersectionReceiver.newIntersections()is invoked when a newIntersectionappears in this map.- Parameters:
pathId- theIdof thePathto monitor- Throws:
NullArgumentException-pathIdisnullOperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForChangedIntersections
Registers for notification of updated intersections.IntersectionReceiver.changedIntersections()is invoked when an intersection in this map is changed.- Throws:
OperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForChangedIntersectionsForPath
void registerForChangedIntersectionsForPath(Id pathId) throws OperationFailedException, PermissionDeniedException Register for notifications of updated intersections for the given path.IntersectionReceiver.changedIntersections()is invoked when an intersection is changed in this map.- Parameters:
pathId- theIdof thePathto monitor- Throws:
NullArgumentException-pathIdisnullOperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForChangedIntersection
void registerForChangedIntersection(Id intersectionId) throws OperationFailedException, PermissionDeniedException Registers for notification of an updated intersection.IntersectionReceiver.changedIntersections()is invoked when the specified intersection in this map is changed.- Parameters:

NullArgumentException-intersectionIdisnullOperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForDeletedIntersections
Registers for notification of deleted intersections.IntersectionReceiver.deletedIntersection()is invoked when an intersection is deleted or removed from this map.- Throws:
OperationFailedException- unable to complete requestPermissionDeniedException- authorization failure- Compliance:
mandatory- This method must be implemented.
-
registerForDeletedIntersectionsForPath
void registerForDeletedIntersectionsForPath(Id pathId) throws OperationFailedException, PermissionDeniedException Register for notifications of deleted intersections for the given path.IntersectionReceiver.deletedIntersections()is invoked when an intersection is removed from this map.- Parameters:
