Interface SignalMapAssignmentSession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

public interface SignalMapAssignmentSession
extends OsidSession

This session provides methods to re-assign Signals to Map objects A Signal may appear in multiple Map objects and removing the last reference to a Signal 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 Signal to another Map is not a copy operation (eg: does not change its Id ).

Method Details

canAssignSignals

boolean canAssignSignals()

Tests if this user can alter signal/map mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known signal 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 signal is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canAssignSignalsToMap

boolean canAssignSignalsToMap(Id mapId)

Tests if this user can alter signal/map mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known signal 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 signal 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.

getAssignableMapIdsForSignal

IdList getAssignableMapIdsForSignal(Id mapId,
 Id signalId)
                             throws OperationFailedException

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

Parameters:

mapId - the Id of the Map

signalId - the Id of the Signal

Returns:

list of assignable map Ids

Throws:

NullArgumentException - mapId or signalId is null

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

assignSignalToMap

void assignSignalToMap(Id signalId,
 Id mapId)
                throws AlreadyExistsException,
NotFoundException,
OperationFailedException,
PermissionDeniedException

Adds an existing Signal to a Map .

Parameters:

signalId - the Id of the Signal

mapId - the Id of the Map

Throws:

AlreadyExistsException - signalId is already assigned to mapId

NotFoundException - signalId or mapId not found

NullArgumentException - signalId or mapId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

unassignSignalFromMap

void unassignSignalFromMap(Id signalId,
 Id mapId)
                    throws NotFoundException,
OperationFailedException,
PermissionDeniedException

Removes a Signal from a Map .

Parameters:

signalId - the Id of the Signal

mapId - the Id of the Map

Throws:

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

NullArgumentException - signalId or mapId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.
