Interfaceosid.cataloging.CatalogLookupSession
Implementsosid.OsidSession
Description

This session provides methods for retrieving Catalog objects. The Catalog represents a collection of OSID Ids.

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

Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. For example, a browsing application may only need to examine the Catalogs it can access, without breaking execution. However, an assessment may only be useful if all Catalogs referenced by it are available, and a test-taking applicationmay sacrifice some interoperability for the sake of precision.

MethodcanLookupCatalogs
Description

Tests if this user can perform Catalog 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.
MethoduseComparativeCatalogView
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.
MethodusePlenaryCatalogView
Description

A complete view of the Catalog 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.
MethodgetCatalog
Description

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

MethodgetCatalogsByIds
Description

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