Interface ObstacleMapAssignmentSession

All Superinterfaces:

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

public interface ObstacleMapAssignmentSession
extends OsidSession

This session provides methods to re-assign Obstacles to Map objects An Obstacle may appear in multiple Map objects and removing the last reference to an Obstacle is the equivalent of deleting it. Each Map may have its own authorizations governing who is allowed to operate on it.

Adding a reference of an Obstacle to another Map is not a copy operation (eg: does not change its Id ).

Method Detail

canAssignObstacles

boolean canAssignObstacles()

Tests if this user can alter obstacle/map mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping 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 assignment operations to unauthorized users.

Returns:

false if mapping is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canAssignObstaclesToMap

boolean canAssignObstaclesToMap(Id mapId)

Tests if this user can alter obstacle/map mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping 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 assignment operations to unauthorized users.

Parameters:

mapId - the Id of the Map

Returns:

false if mapping is not authorized, true otherwise

Throws:

NullArgumentException - mapId is null

Compliance:

mandatory - This method must be implemented.

getAssignableMapIds

IdList getAssignableMapIds(Id mapId)
                           throws OperationFailedException

Gets a list of maps including and under the given map node in which any obstacle can be assigned.

Parameters:

mapId - the Id of the Map

Returns:

list of assignable map Ids

Throws:

NullArgumentException - mapId is null

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

getAssignableMapIdsForObstacle

IdList getAssignableMapIdsForObstacle(Id mapId,
                                    Id obstacleId)
                                      throws OperationFailedException

Gets a list of maps including and under the given map node in which a specific obstacle can be assigned.

Parameters:

mapId - the Id of the Map

obstacleId - the Id of the Obstacle

Returns:

list of assignable map Ids

Throws:

NullArgumentException - mapId or obstacleId is null

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

assignObstacleToMap

void assignObstacleToMap(Id obstacleId,
                       Id mapId)
                         throws AlreadyExistsException,
                                NotFoundException,
                                OperationFailedException,
                                PermissionDeniedException

Adds an existing Obstacle to a Map.

Parameters:

obstacleId - the Id of the Obstacle

mapId - the Id of the Map

Throws:

AlreadyExistsException - obstacleId is already assigned to mapId

NotFoundException - obstacleId or mapId not found

NullArgumentException - obstacleId or mapId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

unassignObstacleFromMap

void unassignObstacleFromMap(Id obstacleId,
                           Id mapId)
                             throws NotFoundException,
                                    OperationFailedException,
                                    PermissionDeniedException

Removes an Obstacle from a Map.

Parameters:

obstacleId - the Id of the Obstacle

mapId - the Id of the Map

Throws:

NotFoundException - obstacleId or mapId not found or obstacleId not assigned to mapId

NullArgumentException - obstacleId or mapId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.
