   AENodeDescriptor^ get();
   void set (    AENodeDescriptor^ value);
}

Property Value

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

Remarks

Because the OpcLabs.EasyOpc.AlarmsAndEvents.AENodeDescriptor has an implicit conversion from System.String and OpcLabs.EasyOpc.AlarmsAndEvents.AddressSpace.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 OpcLabs.EasyOpc.AlarmsAndEvents.AddressSpace.AENodeElement object (result from OPC browsing), in place of OpcLabs.EasyOpc.AlarmsAndEvents.AENodeDescriptor value when setting this property, 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.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
