The OPC UA application manifest, i.e. the application registration information together with data related to PKI administration, such as paths to the certificate stores used.
Syntax
Property Value
The value of this property cannot be null
(Nothing
in Visual Basic).
Because OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement has an implicit conversion to OpcLabs.EasyOpc.UA.UAEndpointDescriptor, you can simply use the returned OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement in any place where OpcLabs.EasyOpc.UA.UAEndpointDescriptor is expected as input, and the corresponding endpoint descriptor will be constructed automatically from the application element. When the implicit conversion operators are not supported (such as with Python.NET), you can use the ToUAEndpointDescriptor static method instead.
Exceptions

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. |
