Detailed Description

UaSessionCallback defines the callback interface for the UaSession class. This callback interface needs to be implemented by the user of the UaSession class to receive connection status change callbacks from the Client SDK. The interface provides also the callback functions for the asynchronous service calls. Only the callbacks for used asynchronous calls need to be implemented by the user of the SDK.
Callbacks from the SDK APIs are coming from worker threads and not from the thread that was used to connect to the server. It is in the responsibility of the user of the client API to syncronize the data provided by the callbacks with a GUI main thread if this is necessary.
