public class FileControlPacket
extends FilePacket

 file control packet.file control packet has a common format, only fewness packet form si defferent
 1. 16 byte session key and QQ number md5 form, use to session key in file transfer 
 2. command type, 2 byte
 3. sequence number, 2 byte
 4. sending time, 4 byte
 5. a unknown byte 0 
 6. sender face, 1 byte
 7. 19 unused byte, all 0
 8. fixed byte 0x65
 9. 1 unknown byte, maybe is connection mode
 10. Internet Ip, 4 byte
 11. Internet port, 2 byte
 13. first monitor port, 2 byte
 14. real IP, 4 byte
 15. second monitor port, 2 byte

 total is 61 byte

 for some command type, haven't part10-15, but at part9 follow a unknown byte, this unknown byte since 
 need original sample return, such command is 0x0031, 0x0032, 0x0033, 0x0034
  
 文件控制信息包，文件控制信息包有一个很普遍的格式，只有少数包的格式有所不同
 1. 16个字节的session key和qq号的md5形式，用来做为文件传输时的会话密钥
 2. 命令类型，2字节
 3. 序号，2字节
 4. 发送时间，4字节
 5. 一个未知字节0
 6. 发送者头像，1字节
 7. 19个未用字节，全0
 8. 固定字节0x65
 9. 1个未知字节，可能是连接方式
 10. 外部IP，4字节
 11. 外部端口，2字节
 13. 第一个监听端口，2字节
 14. 真实IP，4字节
 15. 第二个监听端口，2字节
 
 一共61字节
 
 对于有些命令类型，不存在10－15部分，而是在9部分之后带一个未知字节，这个未知字节似乎
 需要原样返回，这样的命令有0x0031, 0x0032, 0x0033, 0x0034

Constructor Detail

FileControlPacket

public FileControlPacket(FileWatcher watcher)

create a fil control packet object 构造一个文件控制信息包对象

Parameters:

watcher - FileWatcher对象 //object

Method Detail

fill

protected void fill(ByteBuffer out)

Description copied from class: FilePacket

 initialize packet content, subclass should overide this method, and first use this method in super class
     × content of input ByteBuffer will be clear, after complete, buffer position equal to packet length
 初始化包内容，子类应该覆盖这个方法，并首先调用父类的这个方法
 输入ByteBuffer原来的内容将被清空，完成后，buffer的position
 等于包长
 

Overrides:

fill in class FilePacket

Parameters:

out - ByteBuffer对象，做为输出缓冲区 // ByteBuffer object, use to output buffer

fill

protected void fill(ByteBuffer out,
                    int from)

Description copied from class: FilePacket

 initialize packet content, subclass should overide this method, and first use this method in super class
 content of input ByteBuffer won't be clear, new content start fill from from position, after complete,
 buffer position = packet length + from
 初始化包内容，子类应该覆盖这个方法，并首先调用父类的这个方法
 输入ByteBuffer的原来内容不被清空，新的内容从from位置开始
 填充，完成后，buffer的position等于包长加上from
 

Overrides:

fill in class FilePacket

Parameters:

out - ByteBuffer对象，做为输出缓冲区 // ByteBuffer object, use to output buffer

from - 开始填充的位置 //start fill position

parse

protected void parse(ByteBuffer in)
              throws PacketParseException

Description copied from class: FilePacket

parse packet header, subclass should overide this method, and first use this method in super class parse start from current position of in, after parse complete, position of in will be after this packet 解析包头，子类应该覆盖该方法，并首先调用父类的这个方法 解析从in的当前位置开始，解析完毕后in的position将位于 这个包之后
