UASubscribeDataSetFilter Constructor(UASubscribeDataSetFilter)

Filter to be copied from.

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 a UAPublisherId (containing the publisher Id that you want to allow in the filter) in place of this parameter, 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 FromUAPublisherId static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

Initializes a new copy of the object.
