parsedata.java

用java写编写的一个GPS源代码请大家多多指教

package com.gps.center.baseclass;

import java.util.LinkedList;
import java.util.Hashtable;
import com.gps.center.baseclass.MsgObj;
/*
 父类：
   定义：两个Hashtable，centerMap存贮索引车台号码，值为终端TCP-KEY，
                          classMap存贮索引类名，值为对应类的实例
        两个LinkedList：recieveQueue接收消息的队列，sendQueue发送消息的队列
        String型中心IP和端口，final int型消息类型标识，
  方法：对队列的添加，删除，获取

       cMsgtype:1--TCPMSG,2--DEVICEUDPMSG,3--SMSMSG
       4--TCPSENDTODEVICE,5--UDPSENDTODEVICE,6--SMSSENDTODEVICE,7--TCPSENDTOTERMINAL,8--TCPRETURNTERMINAL
