    使用默认包装器创建一个新实例（ ZlibWrapper.ZLIB ）。
    
    异常
    
    DecompressionException - 如果初始化zlib失败
  - JZlibDecoder
```
public JZlibDecoder(ZlibWrapper wrapper)

    用指定的包装器创建一个新的实例。
    
    异常
    
    DecompressionException - 如果初始化zlib失败
  - JZlibDecoder
```
public JZlibDecoder(byte[] dictionary)
```
    用指定的预设字典创建一个新实例。包装始终是ZlibWrapper.ZLIB，因为它是唯一支持预设字典的格式。
    
    异常
    
    DecompressionException - 如果初始化zlib失败

  - isClosed
```
public boolean isClosed()
```
    返回 true当且仅当已达到压缩流的结尾。

               throws java.lang.Exception
```
    从类复制的描述： ByteToMessageDecoder
    
    解码从一个ByteBuf到另一个。这个方法将被调用，直到输入ByteBuf从这个方法返回时没有任何东西可读，或者直到从输入ByteBuf没有读到任何东西。

    decode 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 - 发生错误时抛出
