OSID - osid.mapping.LocationNotificationSession Service Interface Definition

Interface	osid.mapping.LocationNotificationSession
Implements	`osid.OsidSession`
Description	This session defines methods to receive notifications on adds/changes to `Location` objects in this `Map.` This also includes existing locations that may appear or disappear due to changes in the `Location` 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 `LocationLookupSession.`
Method	getMapId
Description	Gets the `Map` `Id` associated with this session.
Return	`osid.id.Id`		the `Map Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getMap
Description	Gets the `Map` associated with this session.
Return	`osid.mapping.Map`		the map
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canRegisterForLocationNotifications
Description	Tests if this user can register for `Location` 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.
Return	`boolean`		`false` if notification methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
