Interfaceosid.workflow.WorkLookupSession
Implementsosid.OsidSession
Description

This session provides methods for retrieving Work objects. The Work represents a fixed connection between two Availabilities.

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 work methods in this session operate, retrieve and pertain to works defined explicitly in the current office. Using an isolated view is useful for managing Works with the WorkAdminSession.
  • federated office view: All work methods in this session operate, retrieve and pertain to all works defined in this office and any other works 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.

MethodgetOfficeId
Description

Gets the Office Id associated with this session.

Returnosid.id.Idthe Office Id associated with this session
CompliancemandatoryThis method must be implemented.
MethodgetOffice

MethodcanLookupWorks
Description

Tests if this user can perform Work 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.

Returnboolean false if lookup methods are not authorized, true otherwise
CompliancemandatoryThis method must be implemented.
MethoduseComparativeWorkView
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.

CompliancemandatoryThis method is must be implemented.
MethodusePlenaryWorkView
Description

A complete view of the Work 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.

CompliancemandatoryThis method is must be implemented.
MethoduseFederatedOfficeView
Description

Federates the view for methods in this session. A federated view will include works in offices which are children of this office in the office hierarchy.

CompliancemandatoryThis method is must be implemented.
MethoduseIsolatedOfficeView
Description

Isolates the view for methods in this session. An isolated view restricts lookups to this office only.

CompliancemandatoryThis method is must be implemented.
MethodgetWork
Description

Gets the Work specified by its Id. In plenary mode, the exact Id is found or a NOT_FOUND results. Otherwise, the returned Work may have a different Id than requested, such as the case where a duplicate Id was assigned to a Work and retained for compatibility.

Parametersosid.id.IdworkId Id of the Work
Returnosid.workflow.Workthe work
ErrorsNOT_FOUND workId not found
NULL_ARGUMENT workId is null
OPERATION_FAILEDunable to complete request

CompliancemandatoryThis method is must be implemented.
MethodgetWorksByIds
Description

Gets a WorkList corresponding to the given IdList. In plenary mode, the returned list contains all of the works 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 Works may be omitted from the list and may present the elements in any order including returning a unique set.

Parametersosid.id.IdListworkIdsthe list of Ids to retrieve

MethodgetWorksByGenusType
Description

Gets a WorkList corresponding to the given work genus Type which does not include works of genus types derived from the specified Type. In plenary mode, the returned list contains all known works or an error results. Otherwise, the returned list may contain only those works that are accessible through this session.
