OSID - osid.mapping.path.PathSpatialDesignSession Service Interface Definition

Interface	osid.mapping.path.PathSpatialDesignSession
Implements	`osid.OsidSession`
Description	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	getMapId
Description	Gets the `Map` `Id` associated with this session.
Return	`osid.id.Id`		the `Map Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getMap
Description	Gets the `Map` associated with this session.
Return	`osid.mapping.Map`		the map
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupPaths
Description	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.
Return	`boolean`		`false` if lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useFederatedMapView
Description	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.
Method	useIsolatedMapView
Description	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.
Method	anchorPathToCoordinate

Parameters	`osid.mapping.Coordinate`	`coordinate`	a coordinate
Errors	NOT_FOUND		no `Path` found
	NULL_ARGUMENT		`pathId` or `coordinate` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		`coordinate` not supported
Compliance	`mandatory`		This method must be implemented.
Method	clearCoordinatesFromPath
Description	Clears the fixed coordinates from a path within the given coordinate.
Parameters	`osid.id.Id`	`pathId`	a path `Id`
Parameters	`osid.mapping.Coordinate`	`coordinate`	a coordinate
Errors	NOT_FOUND		no `Path` found
	NULL_ARGUMENT		`pathId` or `coordinate` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		`coordinate` not supported
Compliance	`mandatory`		This method must be implemented.
Method	getPathCoordinates
Description	Gets a list of fixed path coordinates between the given coordinates along a path inclusive.
Parameters	`osid.id.Id`	`pathId`	a path `Id`
	`osid.mapping.Coordinate`	`from`	a coordinate
	`osid.mapping.Coordinate`	`to`	a coordinate
Return	`osid.mapping.CoordinateList`		the returned `Coordinates`
Errors	NOT_FOUND		no `Path` found
	NULL_ARGUMENT		`pathId, from` or `to` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		`from` or `to` not supported
Compliance	`mandatory`		This method must be implemented.
Method	setPathWidth
Description	Sets the width of the path between two coordinates.
Parameters	`osid.id.Id`	`pathId`	a path `Id`
	`osid.mapping.Distance`	`width`	a width
	`osid.mapping.Coordinate`	`from`	a coordinate
	`osid.mapping.Coordinate`	`to`	a coordinate
Errors	NOT_FOUND		no `Path` found
	NULL_ARGUMENT		`pathId, width, from` or `to` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
	UNSUPPORTED		`from` or `to` not supported
Compliance	`mandatory`		This method must be implemented.
