This type is deprecated since QtOpcUa 6.9. We strongly advise against using it in new code.
import QtOpcUa as QtOpcUa
QtOpcUa.NodeId {
identifier: "s=Example.Node"
ns: "Example Namespace"
}identifier : string
Identifier of the node. The identifier has to be given in one of the following types.
| Type | Example |
|---|---|
| Numeric | i=23 |
| String | s=MyStringIdentifier |
| GUID | g=08081e75-8e5e-319b-954f-f3a7613dc29b |
| Opaque (base64) | b=UXQgZnR3IQ== |
It is possible but not recommended to include the namespace index ns=X;s=.... In this case the given namespace index is internally stripped off the identifier and set to the namespace property.
ns : string
Namespace of the node identifier. The identifier can be the index as a number or the name as string. A string which can be converted to an integer is considered a namespace index.
nodeChanged()
Emitted when the underlying node has changed. This happens when the namespace or identifier has changed.
Note: The corresponding handler is onNodeChanged.
