onBufferProcessedWithTextLines method of the RTRTextCaptureServiceDelegate protocol
Notifies the delegate that a frame was recognized, delivers the result and its stability status.
The result stability status is also provided and should be used to determine if the accuracy is high enough for the result to be used for any practical purposes. We recommend not to use the data in any way until stability level has reached RTRResultStabilityAvailable. When stability of the result has reached the desired level, the service may be stopped by calling the stopTasks method of the RTRTextCaptureService protocol.
This method is to be implemented on the client side. The implementation of this method will probably contain assessing the result plausibility, displaying the results to the user or using them in any way you need.
