OSID - osid.mapping.path.rules.ObstacleEnablerLookupSession Service Interface Definition

Interface	osid.mapping.path.rules.ObstacleEnablerLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `ObstacleEnablers.` This session defines views that offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete set or is an error condition isolated map view: All obstacle enabler methods in this session operate, retrieve and pertain to obstacle enabler defined explicitly in the current map. Using an isolated view is useful for managing `ObstacleEnablers` with the `ObstacleEnablerAdminSession.` federated map view: All obstacle enabler methods in this session operate, retrieve and pertain to all obstacle enabler defined in this map and any other obstacle enabler implicitly available in this map through map inheritence. active obstacle enabler view: All obstacle enabler lookup methods return active obstacle enablers. any status obstacle enabler view: Obstacle enablers of any active or inactive status are returned from methods. Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods `useFederatedMapView()` and `useIsolatedMapView()` behave as a radio group and one should be selected before invoking the methods in this session.
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	canLookupObstacleEnablers
Description	Tests if this user can perform `ObstacleEnablers` lookups. 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 lookup operations to unauthorized users.
Return	`boolean`		`false` if lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeObstacleEnablerView
Description	The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
Compliance	`mandatory`		This method is must be implemented.
Method	usePlenaryObstacleEnablerView
Description	A complete view of the `ObstacleEnabler` returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.
Compliance	`mandatory`		This method is must be implemented.
Method	useFederatedMapView
Description	Federates the view for methods in this session. A federated view will include obstacle enabler in map which are children of this map in the map hierarchy.
Compliance	`mandatory`		This method is must be implemented.

Compliance	`mandatory`		This method is must be implemented.
Method	useActiveObstacleEnablerView
Description	Only active obstacle enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.

Description	All active and inactive obstacle enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	getObstacleEnabler
Description	Gets the `ObstacleEnabler` specified by its `Id.` In plenary mode, the exact `Id` is found or a `NOT_FOUND` results.
