The AEAcknowledgeConditionObserver is an observer that acknowledges OPC event conditions according to incoming values.

Each OnNext method call on its IObserver<AEAcknowledgeConditionArguments> interface acknowledges an OPC event condition according to the arguments passed to it. OnCompleted and OnError methods do nothing.

You can create instances of AEAcknowledgeConditionObserver either by using its constructor, or with use of several overloads of the static Create method. The static AEAcknowledgeConditionObserver.Create methods use the default underlying EasyAEClient object for OPC reactive extensions. If you need to set some parameters in the client object, you can use the ClientSelector property to specify them. This allows the code be expressed only in terms of pure OPC logic, and be not tied to the actual way it is implemented.

It is recommended that you create the instances using the AEAcknowledgeConditionObserver.Create methods unless you have special needs.
