13.3 日志事件POJO

    我们的应用程序通常需要某种“消息POJO”用于保存消息，我们把这个消息POJO看成是一个“事件消息”在本例子中我们也创建一个POJO叫做LogEvent，LogEvent用来存储事件数据，然后将数据输出到日志文件。看下面代码：

[java] view plaincopy

1. package netty.in.action.udp;
3. import java.net.InetSocketAddress;
5. public class LogEvent {
7. public static final byte SEPARATOR = (byte) '|';
9. private final InetSocketAddress source;
10. private final String logfile;
11. private final String msg;
12. private final long received;
14. public LogEvent(String logfile, String msg) {
15. this(null, -1, logfile, msg);
16. }
18. public LogEvent(InetSocketAddress source, long received, String logfile, String msg) {
19. this.source = source;
20. this.logfile = logfile;
21. this.msg = msg;
22. this.received = received;
23. }
25. public InetSocketAddress getSource() {
26. return source;
27. }
29. public String getLogfile() {
30. return logfile;
31. }
33. public String getMsg() {
34. return msg;
35. }
37. public long getReceived() {
38. return received;
39. }
41. }

接下来的章节，我们将用这个POJO类来实现具体的逻辑。
