AEEventType Constructor(AEEventType)



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.AlarmsAndEvents Namespace > AEEventType Class > AEEventType Constructor : AEEventType Constructor(AEEventType)
An AEEventType object to copy from.

Because the AEEventType has an implicit conversion from System.Int64 and AEEventTypes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the numerical value of the event types), or an element of the AEEventTypes enumeration (or a combination of AEEventTypes flags) in place of this parameter, and the corresponding event type specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the AEEventType Constructor(Int64) or AEEventType Constructor(AEEventTypes) constructor instead.

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

Initializes a new instance of the class, from other AEEventType.

Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Requirements

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