All Superinterfaces:

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

public interface UtilityHierarchyDesignSession
extends OsidSession

This session manages a hierarchy of utilities. Utilities may be organized into a hierarchy for organizing or federating. A parent Utility includes all of the Ids of its children such that a single root node contains all of the Ids of the federation.

Method Detail

getUtilityHierarchyId

Id getUtilityHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getUtilityHierarchy

Hierarchy getUtilityHierarchy()
                              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:

canModifyUtilityHierarchy

boolean canModifyUtilityHierarchy()

Tests if this user can change the hierarchy. A return of true does not guarantee successful authorization. A return of false indicates that it is known performing any update will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer these operations to an unauthorized user.

Returns:

false if changing this hierarchy is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.
