AENodeElement Constructor(AENodeDescriptor)



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.AlarmsAndEvents.AddressSpace Namespace > AENodeElement Class > AENodeElement Constructor : AENodeElement Constructor(AENodeDescriptor)
Node descriptor to be copied from.

Because the OpcLabs.EasyOpc.AlarmsAndEvents.AENodeDescriptor has an implicit conversion from System.String and AENodeElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the qualified name of the node), or a AENodeElement object (result from OPC browsing), in place of this parameter, and the corresponding OPC A&E node descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromString or FromAENodeElement static method instead.

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

Initializes a new instance of the class from OpcLabs.EasyOpc.AlarmsAndEvents.AENodeDescriptor.
