Interface AccountHierarchySession

All Superinterfaces:

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

public interface AccountHierarchySession
extends OsidSession

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

Method Detail

getAccountHierarchyId

Id getAccountHierarchyId()

Gets the hierarchy Id associated with this session.

canAccessAccountHierarchy

boolean canAccessAccountHierarchy()

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