UAWriterGroupDescriptor Constructor(UAWriterGroupDescriptor)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UAWriterGroupDescriptor Class > UAWriterGroupDescriptor Constructor : UAWriterGroupDescriptor Constructor(UAWriterGroupDescriptor)
Descriptor for a writer group (using physical Id, or logical name).

Because the UAWriterGroupDescriptor has implicit conversions from System.Int32 and System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the writer group Id), or a string (representing the name of the writer group) in place of this parameter, and the corresponding OPC UA writer group descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromInt32 or FromString static method instead.

Also, because the OpcLabs.EasyOpc.UA.PubSub.Configuration.UAWriterGroupElement has an implicit conversion to UAWriterGroupDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.PubSub.Configuration.UAWriterGroupElement (from PubSub configuration) in place of this parameter, and the corresponding OPC UA PubSub writer group descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a OpcLabs.EasyOpc.UA.PubSub.Configuration.UAWriterGroupElement to UAWriterGroupDescriptor using the OpcLabs.EasyOpc.UA.PubSub.Configuration.UAWriterGroupElement.ToUAWriterGroupDescriptor static method instead.

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