public class SerialDataEvent extends EventObject
This class provides the serial data event object.
Before using the Pi4J library, you need to ensure that the Java VM in configured with access to the following system libraries:
This library depends on the wiringPi native system library. (developed by Gordon Henderson @ http://wiringpi.com/)
