Modifier and Type	Method and Description
`protected void`	`decode(ChannelHandlerContext ctx, ByteBuf in, java.util.List<java.lang.Object> out)` 解码从一个`ByteBuf`到另一个。
`protected void`	`handlerRemoved0(ChannelHandlerContext ctx)` 在`ByteToMessageDecoder`从实际上下文中移除之后调用，它不再处理事件。
`boolean`	`isClosed()` 当且仅当已达到压缩流的结束时才返回 `true` 。

public JdkZlibDecoder()
```
    用默认包装器创建一个新实例（ ZlibWrapper.ZLIB ）。
  - JdkZlibDecoder
```
public JdkZlibDecoder(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。
  - JdkZlibDecoder
```
public JdkZlibDecoder(ZlibWrapper wrapper)
```
    用指定的包装器创建一个新的实例。要知道，只有ZlibWrapper.GZIP ， ZlibWrapper.ZLIB和ZlibWrapper.NONE有ATM支持。
