Interface CourseCatalogHierarchySession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

public interface CourseCatalogHierarchySession
extends OsidSession

This session defines methods for traversing a hierarchy of CourseCatalog objects. Each node in the hierarchy is a unique CourseCatalog. The hierarchy may be traversed recursively to establish the tree structure through getParentCourseCatalogs() and getChildCourseCatalogs(). To relate these Ids to another OSID, getCourseCatalogNodes() can be used for retrievals that can be used for bulk lookups in other OSIDs. Any CourseCatalog available in the Course OSID is known to this hierarchy but does not appear in the hierarchy traversal until added as a root node or a child of another node.

A user may not be authorized to traverse the entire hierarchy. Parts of the hierarchy may be made invisible through omission from the returns of getParentCourseCatalogs() or getChildCourseCatalog() in lieu of a PERMISSION_DENIED error that may disrupt the traversal through authorized pathways.

This session defines views that offer differing behaviors when retrieving multiple objects.

• comparative view: course catalog elements may be silently omitted or re-ordered
• plenary view: provides a complete set or is an error condition

Method Detail

getCourseCatalogHierarchyId

Id getCourseCatalogHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getCourseCatalogHierarchy

Hierarchy getCourseCatalogHierarchy()
                                    throws OperationFailedException,
                                           PermissionDeniedException

Gets the hierarchy associated with this session.

Returns:

the hierarchy associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canAccessCourseCatalogHierarchy

boolean canAccessCourseCatalogHierarchy()

Tests if this user can perform hierarchy queries. 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.

Returns:

false if hierarchy traversal methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useComparativeCourseCatalogView

void useComparativeCourseCatalogView()

The returns from the course catalog 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.

usePlenaryCourseCatalogView

void usePlenaryCourseCatalogView()

A complete view of the CourseCatalogs 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.
