- 构造方法详细信息
  - WebSocket00FrameDecoder
```
public WebSocket00FrameDecoder()
```
  - WebSocket00FrameDecoder
```
public WebSocket00FrameDecoder(int maxFrameSize)
```
    用指定的maxFrameSize创建WebSocketFrameDecoder的新实例。如果客户端发送的帧大小大于maxFrameSize ，则该频道将被关闭。
    
    参数
    
    maxFrameSize - 解码的最大帧大小
- 方法详细信息
  - decode
```
protected void decode(ChannelHandlerContext ctx,
                      ByteBuf in,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception
```
    从类复制的描述： ByteToMessageDecoder
    
    解码从一个ByteBuf到另一个。该方法将被调用，直到输入ByteBuf在从此方法返回时没有任何可读的内容或直到从输入ByteBuf中没有读取任何内容。
    
    Specified by:
    
    decode在课堂 ByteToMessageDecoder
    
    参数
    
    ctx - 这ByteToMessageDecoder所属的ChannelHandlerContext
    
    in - 从中读取数据的ByteBuf
    
    out - 应该添加解码消息的 List
    
    异常
    
    java.lang.Exception - is thrown if an error occurs
