Interface PathSpatialDesignSession

All Superinterfaces:

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

public interface PathSpatialDesignSession
extends OsidSession

This session defines methods for designing paths.

This lookup session defines several views:

• isolated map view: All path methods in this session operate, retrieve and pertain to paths defined explicitly in the current map. Using an isolated view is useful for managing Paths with the PathAdminSession.
• federated map view: All path lookup methods in this session operate, retrieve and pertain to all paths defined in this map and any other paths implicitly available in this map through map inheritence.

The methods useFederatedMapView() and useIsolatedMapView() behave as a radio group and one should be selected before invoking any lookup methods.

Method Detail

getMapId

Id getMapId()

Gets the Map Id associated with this session.

Returns:

the Map Id associated with this session

Compliance:

mandatory - This method must be implemented.

getMap

Map getMap()
           throws OperationFailedException,
                  PermissionDeniedException

Gets the Map associated with this session.

Returns:

the map

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canLookupPaths

boolean canLookupPaths()

Tests if this user can perform Path lookups. 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 not offer lookup operations to unauthorized users.

Returns:

false if lookup methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useFederatedMapView

void useFederatedMapView()

Federates the view for methods in this session. A federated view will include paths in maps which are children of this map in the map hierarchy.

Compliance:

mandatory - This method is must be implemented.

useIsolatedMapView

void useIsolatedMapView()

Isolates the view for methods in this session. An isolated view restricts retrievals to this map only.

Compliance:

mandatory - This method is must be implemented.

Compliance:

mandatory - This method must be implemented.

clearCoordinatesFromPath
