public interface OrganizationHierarchySession
extends OsidSession

This session defines methods for traversing a hierarchy of Organization objects. Each node in the hierarchy is a unique Organization. The hierarchy may be traversed recursively to establish the tree structure through getOrganizationNodes(). To relate these Ids to another OSID, getAncestorOrganizations() and getDescendantOrganizations() can be used for retrievals that can be used for bulk lookups in other OSIDs. Any Organization available in the Personnel 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 getParentOrganizations() or getChildOrganizations() 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: organization elements may be silently omitted or re-ordered
• plenary view: provides a complete set or is an error condition

canAccessOrganizationHierarchy

boolean canAccessOrganizationHierarchy()

Tests if this user can perform hierarchy queries. A return of true does not guarantee successful authorization.
