OSID - osid.workflow.rules.StepConstrainerRuleLookupSession Service Interface Definition

Interface	osid.workflow.rules.StepConstrainerRuleLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods to retrieve `StepConstrainer` to `Step` mappings. A `Step` with multiple `StepConstrainers` means any positive rule evaluation across the constrainers result in an accessible `Step.` 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 office view: All methods in this session operate, retrieve and pertain step constrainer defined explicitly in the current office federated office view: All methods in this session operate, retrieve and pertain to all step constrainer defined in this office and any other step constrainer implicitly available in this office through office inheritence.
Method	getOfficeId
Description	Gets the `Office` `Id` associated with this session.
Return	`osid.id.Id`		the `Office Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getOffice
Description	Gets the `Office` associated with this session.
Return	`osid.workflow.Office`		the office
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupStepConstrainerRules
Description	Tests if this user can perform lookups of step constrainer/step mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known lookup 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 looking up mappings is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeStepConstrainerRuleView
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	usePlenaryStepConstrainerRuleView
Description	A complete view of the `StepConstrainer` and `Step` 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	useFederatedOfficeView
Description	Federates the view for methods in this session. A federated view will include step constrainer in offices which are children of this office in the office hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedOfficeView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this office only.
Compliance	`mandatory`		This method is must be implemented.
Method	getStepConstrainerIdsForStep
Description	Gets the `StepConstrainer Id` associated with a `Step.`
Parameters	`osid.id.Id`	`stepId`	`Id` of the `Step`
Return	`osid.id.IdList`		the step constrainer `Ids`
Errors	NOT_FOUND		`stepId` is not found
	NULL_ARGUMENT		`stepId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getStepConstrainersForStep
Description	Gets the `StepConstrainer` associated with a `Step.`
Parameters	`osid.id.Id`	`stepId`	`Id` of the `Step`
Return	`osid.workflow.rules.StepConstrainerList`		the step constrainers
Errors	NOT_FOUND		`stepId` is not found
	NULL_ARGUMENT		`stepId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getStepIdsForStepConstrainer
Description	Gets the `Step` `Ids` mapped to a `StepConstrainer.`
Parameters	`osid.id.Id`	`stepConstrainerId`	`Id` of a `StepConstrainer`
Return	`osid.id.IdList`		list of step `Ids`
Errors	NOT_FOUND		`stepConstrainerId` is not found
	NULL_ARGUMENT		`stepConstrainerId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getStepsForStepConstrainer
Description	Gets the `Steps` mapped to a `StepConstrainer.`
Parameters	`osid.id.Id`	`stepConstrainerId`	`Id` of a `StepConstrainer`
Return	`osid.workflow.StepList`		list of steps
Errors	NOT_FOUND		`stepConstrainerId` is not found
	NULL_ARGUMENT		`stepConstrainerId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
