UAContentFilterElement Constructor(UAContentFilterElement)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Filtering Namespace > UAContentFilterElement Class > UAContentFilterElement Constructor : UAContentFilterElement Constructor(UAContentFilterElement)
Content filter element object to copy from.

Because the UAContentFilterElementBuilder has an implicit conversion to UAContentFilterElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a UAContentFilterElementBuilder in place of this parameter, and the corresponding OPC UA content filter element will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a UAContentFilterElementBuilder to UAContentFilterElement using the UAContentFilterElementBuilder.ToUAContentFilterElement static method instead.

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

Initializes a new instance of the class as a copy of a content filter element.
