Methods

syncAllNodes()

This method synchronizes all nodes (which may have changed dynamically) with the underlying OPC UA server instance.

This method was introduced in InCore 2.6.

syncNode(OpcUaServerNode startNode)

This method recursively synchronizes the given nodes with the underlying OPC UA server instance.

This method was introduced in InCore 2.6.

Signals

namespacesDataChanged(SignedInteger index)

This signal is emitted whenever the List.dataChanged() signal is emitted, i.e. the item at index in the namespaces list itself emitted the dataChanged() signal.

usersDataChanged(SignedInteger index)

This signal is emitted whenever the List.dataChanged() signal is emitted, i.e. the item at index in the users list itself emitted the dataChanged() signal.
