OSID - osid.mapping.path.rules.SpeedZoneEnablerMapAssignmentSession Service Interface Definition

Interface	osid.mapping.path.rules.SpeedZoneEnablerMapAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `SpeedZoneEnabler` to `Map` mappings. a `SpeedZoneEnabler` may appear in multiple `Map` objects and removing the last reference to a `SpeedZoneEnabler` 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 a `SpeedZoneEnabler` to another `Map` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignSpeedZoneEnablers
Description	Tests if this user can alter speed zone enabler/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 lookup operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignSpeedZoneEnablersToMap
Description	Tests if this user can alter speed zone enabler/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 lookup operations to unauthorized users.
Parameters	`osid.id.Id`	`mapId`	the `Id` of the `Map`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`mapId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableMapIds
Description	Gets a list of map including and under the given map node in which any speed zone enabler can be assigned.
Parameters	`osid.id.Id`	`mapId`	the `Id` of the `Map`
Return	`osid.id.IdList`		list of assignable map `Ids`
Errors	NULL_ARGUMENT		`mapId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableMapIdsForSpeedZoneEnabler
Description	Gets a list of map including and under the given map node in which a specific speed zone enabler can be assigned.
Parameters	`osid.id.Id`	`mapId`	the `Id` of the `Map`
Parameters	`osid.id.Id`	`speedZoneEnablerId`	the `Id` of the `SpeedZoneEnabler`
Return	`osid.id.IdList`		list of assignable map `Ids`
Errors	NULL_ARGUMENT		`mapId` or `speedZoneEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignSpeedZoneEnablerToMap
Description	Adds an existing `SpeedZoneEnabler` to an `Map.`
Parameters	`osid.id.Id`	`speedZoneEnablerId`	the `Id` of the `SpeedZoneEnabler`
Parameters	`osid.id.Id`	`mapId`	the `Id` of the `Map`
Errors	ALREADY_EXISTS		`speedZoneEnablerId` is already assigned to `mapId`
	NOT_FOUND		`speedZoneEnablerId` or `mapId` not found
	NULL_ARGUMENT		`speedZoneEnablerId` or `mapId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignSpeedZoneEnablerFromMap
Description	Removes a `SpeedZoneEnabler` from an `Map.`
Parameters	`osid.id.Id`	`speedZoneEnablerId`	the `Id` of the `SpeedZoneEnabler`
Parameters	`osid.id.Id`	`mapId`	the `Id` of the `Map`
Errors	NOT_FOUND		`speedZoneEnablerId` or `mapId` not found or `speedZoneEnablerId` not assigned to `mapId`
	NULL_ARGUMENT		`speedZoneEnablerId` or `mapId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
