Method Detail

addChange

public void addChange(NodeId affectedNodeId,
                      NodeId typeDefinition,
                      int verb)

Add a model change to the event before triggering it.

Parameters:

affectedNodeId - The NodeId of the affected node. If the node is UaNode, use addChange(UaNode, ModelChangeType...) instead.

typeDefinition - the type of the node, in case it is an Object or Variable node

verb - the change types made to the node, defined as a bit set

See Also:

addChange(UaNode, ModelChangeType...), addChange(NodeId, NodeId, ModelChangeType...)

addChange

public void addChange(NodeId affectedNodeId,
                      NodeId typeDefinition,
                      ModelChangeType... changeTypes)

Add a model change to the event before triggering it.

Parameters:

affectedNodeId - The NodeId of the affected node

typeDefinition - the type of the node, in case it is an Object or Variable node

changeTypes - The change type made to the affectedNode

addChange

public void addChange(NodeId affectedNodeId,
                      NodeId typeDefinition,
                      UnsignedByte verb)

Add a model change to the event before triggering it.

Parameters:

affectedNodeId - The NodeId of the affected node. If the node is UaNode, use addChange(UaNode, ModelChangeType...) instead.

typeDefinition - the type of the node, in case it is an Object or Variable node

verb - the change types made to the node, defined as a bit set

See Also:

addChange(UaNode, ModelChangeType...), addChange(NodeId, NodeId, ModelChangeType...)

addChange

public void addChange(UaNode affectedNode,
                      ModelChangeType... changeTypes)

Add a model change to the event before triggering it.

Parameters:

affectedNode - The node that was changed

changeTypes - The change type made to the affectedNode

addChanges

public void addChanges(List<ModelChangeStructureDataType> changes)

Adds a list of changes to the event.

addChanges

public void addChanges(ModelChangeStructureDataType[] changes)

Adds a list of changes to the event.

Parameters:

changes - the changes to add.

clearChanges

public void clearChanges()

Clears the current set of changes. The event is automatically cleared when triggerEvent is called

getAffectedNodes

public UaNode[] getAffectedNodes()

The AffectedNodes is used to keep a list of UaNode objects that are affected by the change and to which the NodeVersion should be updated after the event is sent.

Returns:

affected nodes

getChanges

public ModelChangeStructureDataType[] getChanges()

Returns changes.

hasChanges

public boolean hasChanges()

Returns true if there is at least one change, otherwise false.

hasChanges

public boolean hasChanges(NodeId affectedNode)

Returns true if there is at least once change regarding the given NodeId, false if not.

setChanges

public void setChanges(ModelChangeStructureDataType[] changes)

Sets the list of changes to send. Clears the current chanegs and the calls addChange(NodeId, NodeId, int) for each change in the list.

Parameters:

changes - the list of changes to send with the event.

updateNodeVersions

public void updateNodeVersions()

Updates the NodeVersion property of all getAffectedNodes(). Should be called once before triggering.

addAffectedNode

protected void addAffectedNode(UaNode affectedNode)

Adds the node to affected nodes (if it doesn't already exist there.
