OSID - osid.rules.check.InstructionLookupSession Service Interface Definition

Interface	osid.rules.check.InstructionLookupSession
Implements	`osid.OsidSession`
Used By	`osid.rules.check.RulesCheckManager`
Used By	`osid.rules.check.RulesCheckProxyManager`
Description	This session defines methods for retrieving instructions. This lookup session defines several views: comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete result set or is an error condition isolated engine view: All instruction methods in this session operate, retrieve and pertain to instructions defined explicitly in the current engine. Using an isolated view is useful for managing `Instructions` with the `InstructionAdminSession`. federated engine view: All instruction lookup methods in this session operate, retrieve and pertain to all instructions defined in this engine and any other instructions implicitly available in this engine through engine inheritence. active instruction view: All instruction lookup methods return active instructions. any status instruction view: instructions of any active or inactive status are returned from methods. The methods `useFederatedEngineView()` and `useIsolatedEngineView()` behave as a radio group and one should be selected before invoking any lookup methods. Instructions may have an additional records indicated by their respective record types. The record may not be accessed through a cast of the `Instructions`.
Method	getEngineId
Description	Gets the `Engine` `Id` associated with this session.
Return	`osid.id.Id`		the `Engine Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getEngine
Description	Gets the `Engine` associated with this session.
Return	`osid.rules.Engine`		the engine
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupInstructions
Description	Tests if this user can perform `Instruction` 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 not 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	useComparativeInstructionView
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	usePlenaryInstructionView
Description	A complete view of the `Instruction` 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	useFederatedEngineView
Description	Federates the view for methods in this session. A federated view will include instructions in engines which are children of this engine in the engine hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedEngineView
Description	Isolates the view for methods in this session. An isolated view restricts retrievals to this engine only.
Compliance	`mandatory`		This method is must be implemented.
Method	useActiveInstructionView
Description	Only active instructions are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useAnyStatusInstructionView
Description	All active and inactive instructions of are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	getInstruction
Description	Gets the `Instruction` specified by its `Id`. In plenary mode, the exact `Id` is found or a `NOT_FOUND` results.
