Interface BillingHierarchySession

All Superinterfaces:

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

public interface BillingHierarchySession
extends OsidSession

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

Method Detail

getBillingHierarchyId

Id getBillingHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getBillingHierarchy

Hierarchy getBillingHierarchy()
                              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.

canAccessBillingHierarchy

boolean canAccessBillingHierarchy()

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.

useComparativeBillingView

void useComparativeBillingView()

The returns from the billing 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.

usePlenaryBillingView

void usePlenaryBillingView()

A complete view of the Billing 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.

getRootBillingIds
