034 * <p>This interface implements the callback event handler for GPIO interrupt state changes.</p>
035 *
036 * <p>
037 * Before using the Pi4J library, you need to ensure that the Java VM in configured with access to
038 * the following system libraries:
039 * <ul>
040 * <li>pi4j</li>
041 * <li>wiringPi</li>
042 * </ul>
043 * <blockquote> This library depends on the wiringPi native system library.</br> (developed by
