public class PromptInputStream
extends RoutedInputStream

The PromptInputStream reads from an inputstream until it reads any prompt for which a listener is added. The listener is informed that the prompt is found. The route which contains the prompt is supplied as a parameter to the listener. Returning from the prompt listener without reading the route to its end will allow the main stream to read it. The implementation of this class is based on the RoutedInputStream.
