Interface OfficeHierarchySession

All Superinterfaces:

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

public interface OfficeHierarchySession
extends OsidSession

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

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 getParentOffices() or getChildOffices() in lieu of a PERMISSION_DENIED error that may disrupt the traversal through authorized stepways.

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

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

Method Detail

getOfficeHierarchyId

Id getOfficeHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getOfficeHierarchy

Hierarchy getOfficeHierarchy()
                             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.

canAccessOfficeHierarchy

boolean canAccessOfficeHierarchy()

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.

useComparativeOfficeView

void useComparativeOfficeView()

The returns from the 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.

usePlenaryOfficeView

void usePlenaryOfficeView()

A complete view of the Offices 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.
