Interface FrontOfficeHierarchySession

All Superinterfaces:

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

public interface FrontOfficeHierarchySession
extends OsidSession

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

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 getParentFrontOffices() or getChildFrontOffices() in lieu of a PERMISSION_DENIED error that may disrupt the traversal through authorized effortways.

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

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

Method Detail

getFrontOfficeHierarchyId

Id getFrontOfficeHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getFrontOfficeHierarchy

Hierarchy getFrontOfficeHierarchy()
                                  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.

canAccessFrontOfficeHierarchy

boolean canAccessFrontOfficeHierarchy()

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.

useComparativeFrontOfficeView

void useComparativeFrontOfficeView()

The returns from the front office 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.

usePlenaryFrontOfficeView

void usePlenaryFrontOfficeView()

A complete view of the FrontOffices 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.
