'Declaration<CanBeNullAttribute()> <ContractAnnotationAttribute("null => null; notnull => notnull")> Overloads Public Operator Widening CType( _ ByVal nodeIdExpandedText As String _ ) As UANodeDescriptor
'Usage
[CanBeNull()] [ContractAnnotation("null => null; notnull => notnull")] public UANodeDescriptor operator implicit( string nodeIdExpandedText )
[CanBeNull()] [ContractAnnotation("null => null; notnull => notnull")] public: operator UANodeDescriptor^ ( String^ nodeIdExpandedText )
Parameters
- nodeIdExpandedText
- An node Id expanded text (contains namespace URI, and namespace-relative node Id).
The value represents an expanded text of an OPC UA node Id. Any string can be passed to this parameter (i.e. will not cause System.ArgumentException), but not all values make sense and will work when an operation using them is attempted. Example of node Id expanded texts are "nsu=http://test.org/UA/Data/;i=10853" or "ns=1;s=SomeNode".
The value of this parameter can be
null(Nothingin Visual Basic).
Return Value
null if the input is null.
Because there are implicit conversions to OpcLabs.EasyOpc.UA.Navigation.UANamedNodeDescriptor and OpcLabs.EasyOpc.UA.Navigation.UANamedNodePath from UANodeDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UANodeDescriptor in any place where OpcLabs.EasyOpc.UA.Navigation.UANamedNodeDescriptor is expected (in this case the UANodeDescriptor contains the final node descriptor) or where OpcLabs.EasyOpc.UA.Navigation.UANamedNodePath is expected (in this case the UANodeDescriptor contains the base and only node in the named node path), and the corresponding OPC UA named node descriptor or named node path will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.Navigation.UANamedNodeDescriptor.FromUANodeDescriptor or OpcLabs.EasyOpc.UA.Navigation.UANamedNodePath.FromUANodeDescriptor static method instead.
This method can return null (Nothing in Visual Basic).
