OSID - osid.control.rules.TriggerEnablerLookupSession Service Interface Definition

Interface	osid.control.rules.TriggerEnablerLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `TriggerEnablers.` 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 system view: All trigger enabler methods in this session operate, retrieve and pertain to trigger enablers defined explicitly in the current system. Using an isolated view is useful for managing `TriggerEnablers` with the `TriggerEnablerAdminSession.` federated system view: All trigger enabler methods in this session operate, retrieve and pertain to all trigger enablers defined in this system and any other trigger enablers implicitly available in this system through system inheritence. activee trigger enabler view: All trigger enabler lookup methods return active trigger enablers. any status trigger enabler view: trigger 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 `useFederatedDistributorView()` and `useIsolatedDistributorView()` behave as a radio group and one should be selected before invoking the methods in this session.
Method	getSystemId
Description	Gets the `System` `Id` associated with this session.
Return	`osid.id.Id`		the `System Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getSystem
Description	Gets the `System` associated with this session.
Return	`osid.control.System`		the system
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupTriggerEnablers
Description	Tests if this user can perform `TriggerEnablers` 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	useComparativeTriggerEnablerView
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	usePlenaryTriggerEnablerView
Description	A complete view of the `TriggerEnabler` 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	useFederatedSystemView
Description	Federates the view for methods in this session. A federated view will include trigger enablers in systems which are children of this system in the system hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedSystemView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this system only.
Compliance	`mandatory`		This method is must be implemented.
Method	useActiveTriggerEnablerView
Description	Only active trigger enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useAnyStatusTriggerEnablerView
Description	All active and inactive trigger enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	getTriggerEnabler
Description	Gets the `TriggerEnabler` specified by its `Id.` In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `TriggerEnabler` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `TriggerEnabler` and retained for compatibility. In active mode, trigger enablers are returned that are currently active. In any status mode, active and inactive trigger enablers are returned.

Compliance	`mandatory`		This method is must be implemented.
Method	getTriggerEnablersByIds
Description	Gets a `TriggerEnablerList` corresponding to the given `IdList.` In plenary mode, the returned list contains all of the trigger enablers specified in the `Id` list, in the order of the list, including duplicates, or an error results if an `Id` in the supplied list is not found or inaccessible. Otherwise, inaccessible `TriggerEnablers` may be omitted from the list and may present the elements in any order including returning a unique set. In active mode, trigger enablers are returned that are currently active. In any status mode, active and inactive trigger enablers are returned.
