Interface AntimatroidHierarchySession

All Superinterfaces:

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

public interface AntimatroidHierarchySession
extends OsidSession

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

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 getParentAntimatroids() or getChildAntimatroids() in lieu of a PERMISSION_DENIED error that may disrupt the traversal through authorized featureways.

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

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

Method Detail

getAntimatroidHierarchyId

Id getAntimatroidHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getAntimatroidHierarchy

Hierarchy getAntimatroidHierarchy()
                                  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.

canAccessAntimatroidHierarchy

boolean canAccessAntimatroidHierarchy()

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.

useComparativeAntimatroidView

void useComparativeAntimatroidView()

The returns from the antimatroid 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.
