Interface EdgeEnablerRuleApplicationSession

All Superinterfaces:

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

public interface EdgeEnablerRuleApplicationSession
extends OsidSession

This session provides methods to apply EdgeEnablers to Edges. An Edge with multiple EdgeEnablers means any positive rule evaluation across the enablers result in an effective Edge.

Method Detail

getGraphId

Id getGraphId()

Gets the Graph Id associated with this session.

Returns:

the Graph Id associated with this session

Compliance:

mandatory - This method must be implemented.

getGraph

Graph getGraph()
               throws OperationFailedException,
                      PermissionDeniedException

Gets the Graph associated with this session.

Returns:

the graph

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canAssignEdgeEnablers

boolean canAssignEdgeEnablers()

Tests if this user can alter edge enabler/edge 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.

Returns:

false if mapping is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

assignEdgeEnablerToEdge

void assignEdgeEnablerToEdge(Id edgeEnablerId,
                           Id edgeId)
                             throws AlreadyExistsException,
                                    NotFoundException,
                                    OperationFailedException,
                                    PermissionDeniedException

Adds an existing EdgeEnabler to an Edge.

Parameters:

edgeEnablerId - the Id of the EdgeEnabler

edgeId - the Id of the Edge

Throws:

AlreadyExistsException - edgeEnablerId is already applied to edgeId

NotFoundException - edgeEnablerId or edgeId not found

NullArgumentException - edgeEnablerId or edgeId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

unassignEdgeEnablerFromEdge

void unassignEdgeEnablerFromEdge(Id edgeEnablerId,
                               Id edgeId)
                                 throws NotFoundException,
                                        OperationFailedException,
                                        PermissionDeniedException

Removes an EdgeEnabler from an Edge.

Parameters:

edgeEnablerId - the Id of the EdgeEnabler

edgeId - the Id of the Edge

Throws:

NotFoundException - edgeEnablerId or edgeId not found or edgeEnablerId is not applied to edgeId

NullArgumentException - edgeEnablerId or edgeId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canSequenceEdgeEnablers

boolean canSequenceEdgeEnablers()

Tests if this user can order EdgeEnablers. A return of true does not guarantee successful authorization. A return of false indicates that it is known sequencing operations will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer sequencing operations to an unauthorized user.

Returns:

false if EdgeEnabler ordering is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

moveEdgeEnablerAhead

void moveEdgeEnablerAhead(Id edgeEnablerId,
                        Id edgeId,
                        Id referenceId)
                          throws NotFoundException,
                                 OperationFailedException,
                                 PermissionDeniedException

Reorders edge enablers for an edge by moving the specified edge enabler in front of a reference edge enabler.

Parameters:

edgeEnablerId - the Id of an EdgeEnabler

edgeId - the Id of an Edge

Throws:

NotFoundException - edgeEnablerId, edgeId, or referenceId not found or, edgeEnablerId or referenceId not related to edgeId

NullArgumentException - edgeEnablerId, edgeId, or referenceId is null

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

moveEdgeEnablerBehind

void moveEdgeEnablerBehind(Id edgeEnablerId,
