Parameters
- stringIdentifier
- A string identifier of the publisher Id.
The value of this parameter cannot be
null(Nothingin Visual Basic).
Return Value
Returns a string publisher Id with the specified identifier.
Because the UASubscribeDataSetFilter has an implicit conversion from UAPublisherId, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UAPublisherId (containing the publisher Id that you want to allow in the filter) in any place where UASubscribeDataSetFilter is expected as input, and the corresponding OPC UA subscribe dataset filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UASubscribeDataSetFilter.FromUAPublisherId static method instead.
This method never returns null (Nothing in Visual Basic).
