mylaps-tcp-server

Java TCP server for handling Timing and Scoring data feed. Just override ServerDataHandler and create a new MyLapsTCPServer with that handler.

public class SampleServerHandler extends ServerDataHandler {

    private static final Logger LOG = LoggerFactory.getLogger(SampleServerHandler.class);

    public static void main(String args[]) throws Exception {
        LOG.info("Sample server startup");
        new MyLapsTCPServer(new SampleServerHandler());
    }

    @Override
    public void handlePassings(Collection<Passing> passings) {
        LOG.info("Passings message received");
        for(Passing passing: passings){
            LOG.info("\t"+passing);
        }
    }

    @Override
    public String getServerName() {
        return "SampleServer";
    }

    @Override
    public int getServerPort() {
        return 3097;
    }
}
