Parameters
- client
- The client object that will perform the operation.
This is typically the OpcLabs.EasyOpc.UA.EasyUAClient object.
The value of this parameter cannot be
null
(Nothing
in Visual Basic). - argumentsAndExitPredicateList
- List of tuples, where each tuple consists of OPC-UA monitored item arguments, and a predicate on OpcLabs.EasyOpc.UA.OperationModel.EasyUADataChangeNotificationEventArgs determining when the wait is complete.
The value of this parameter cannot be
null
(Nothing
in Visual Basic).
Return Value
This method never returns null
(Nothing
in Visual Basic).
The individual elements of the returned value are never null
(Nothing
