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

Interface	osid.workflow.rules.ProcessConstrainerLookupSession
Implements	`osid.OsidSession`
Used By	`osid.workflow.rules.WorkflowRulesManager`
Used By	`osid.workflow.rules.WorkflowRulesProxyManager`
Description	This session provides methods for retrieving `ProcessConstrainers` . 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 office view: All process cosntrainer methods in this session operate, retrieve and pertain to process constrainers defined explicitly in the current office Using an isolated view is useful for managing `ProcessConstrainers` with the `ProcessConstrainerAdminSession` . federated office view: All process constrainer methods in this session operate, retrieve and pertain to all process constrainers defined in this office and any other process constrainers implicitly available in this office through office inheritence. 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 `useFederatedOfficeView()` and `useIsolatedOfficeView() behave` as a radio group and one should be selected before invoking any lookup methods.
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	canLookupProcessConstrainers
Description	Tests if this user can perform `ProcessConstrainer` 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	useComparativeProcessConstrainerView
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	usePlenaryProcessConstrainerView
Description	A complete view of the `ProcessConstrainer` 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 process constrainers 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	getProcessConstrainer
Description	Gets the `ProcessConstrainer` specified by its `Id` . In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `ProcessConstrainer` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `ProcessConstrainer and re` tained for compatibility.
Parameters	`osid.id.Id`	`processConstrainerId`	`Id` of the `ProcessConstrainer`
Return	`osid.workflow.rules.ProcessConstrainer`		the process constrainer
Errors	NOT_FOUND		`processConstrainerId` not found
	NULL_ARGUMENT		`processConstrainerId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method is must be implemented.
Method	getProcessConstrainersByIds
Description	Gets a `ProcessConstrainerList` corresponding to the given `IdList` . In plenary mode, the returned list contains all of the process constrainers 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 `ProcessConstrainers may be` omitted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`processConstrainerIds`	the list of `Ids` to retrieve
Return	`osid.workflow.rules.ProcessConstrainerList`		the returned `ProcessConstrainer` list
Errors	NOT_FOUND		an `Id was` not found
	NULL_ARGUMENT		`processConstrainerIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProcessConstrainersByGenusType
Description	Gets a `ProcessConstrainerList` corresponding to the given process constrainer genus `Type` which does not include process constrainers of genus types derived from the specified `Type` . `In` plenary mode, the returned list contains all known process constrainers or an error results. Otherwise, the returned list may contain only those process constrainers that are accessible through this session.
Parameters	`osid.type.Type`	`processConstrainerGenusType`	a process constrainer genus type
Return	`osid.workflow.rules.ProcessConstrainerList`		the returned `ProcessConstrainer` list
Errors	NULL_ARGUMENT		`processConstrainerGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProcessConstrainersByParentGenusType
Description	Gets a `ProcessConstrainerList` corresponding to the given process constrainer genus `Type` and include any additional process constrainers with genus types derived from the specified `Type` . `In` plenary mode, the returned list contains all known process constrainers or an error results. Otherwise, the returned list may contain only those process constrainers that are accessible through this session.
Parameters	`osid.type.Type`	`processConstrainerGenusType`	a process constrainer genus type
Return	`osid.workflow.rules.ProcessConstrainerList`		the returned `ProcessConstrainer` list
Errors	NULL_ARGUMENT		`processConstrainerGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProcessConstrainersByRecordType
Description	Gets a `ProcessConstrainerList` containing the given process constrainer record `Type` . `In` plenary mode, the returned list contains all known process constrainers or an error results. Otherwise, the returned list may contain only those process constrainers that are accessible through this session.
Parameters	`osid.type.Type`	`processConstrainerRecordType`	a process constrainer record type

	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProcessConstrainers
Description	Gets all `ProcessConstrainers` . `In ple` nary mode, the returned list contains all known process constrainers or an error results. Otherwise, the returned list may contain only those process constrainers that are accessible through this session.
