All Superinterfaces:

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

public interface ObjectiveHierarchyDesignSession
extends OsidSession

This session defines methods for managing a hierarchy of Objective objects. Each node in the hierarchy is a unique Objective.

Method Detail

getObjectiveHierarchyId

Id getObjectiveHierarchyId()

Gets the hierarchy Id associated with this session.

Returns:

the hierarchy Id associated with this session

Compliance:

mandatory - This method must be implemented.

getObjectiveHierarchy

Hierarchy getObjectiveHierarchy()
                                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.

canModifyObjectiveHierarchy

boolean canModifyObjectiveHierarchy()

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.

addRootObjective

void addRootObjective(Id objectiveId)
                      throws AlreadyExistsException,
                             NotFoundException,
                             OperationFailedException,
                             PermissionDeniedException

Adds a root objective.

Parameters:

objectiveId - the Id of an objective

Throws:

AlreadyExistsException - objectiveId is already in hierarchy

NotFoundException - objectiveId not found

NullArgumentException - objectiveId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

removeRootObjective

void removeRootObjective(Id objectiveId)
                         throws NotFoundException,
                                OperationFailedException,
                                PermissionDeniedException

Removes a root objective.

Parameters:

objectiveId - the Id of an objective

Throws:

NotFoundException - objectiveId not found

NullArgumentException - objectiveId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

addChildObjective

void addChildObjective(Id objectiveId,
                     Id childId)
                       throws AlreadyExistsException,
                              NotFoundException,

                              PermissionDeniedException

Adds a child to an objective.

Parameters:

objectiveId - the Id of an objective

Throws:

AlreadyExistsException - objectiveId is already a parent of childId

NotFoundException - objectiveId or childId not found

NullArgumentException - objectiveId or childId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

removeChildObjective

void removeChildObjective(Id objectiveId,
                        Id childId)
                          throws NotFoundException,
                                 OperationFailedException,
                                 PermissionDeniedException

Removes a child from an objective.

Parameters:
