Http2StreamFrameToHttpObjectCodec (Netty API Reference (4.1.22.Final))

java.lang.Object
- io.netty.channel.ChannelHandlerAdapter
- - io.netty.channel.ChannelInboundHandlerAdapter
  - - io.netty.channel.ChannelDuplexHandler
    - - io.netty.handler.codec.MessageToMessageCodec<Http2StreamFrame,HttpObject>
      - io.netty.handler.codec.http2.Http2StreamFrameToHttpObjectCodec

All Implemented Interfaces:

ChannelHandler ， ChannelInboundHandler ， ChannelOutboundHandler
```
@UnstableApi
 @ChannelHandler.Sharable
public class Http2StreamFrameToHttpObjectCodec
extends MessageToMessageCodec<Http2StreamFrame,HttpObject>
```
该处理程序从Http2StreamFrame转换为HttpObject ，然后返回。它可以作为适配器与Http2MultiplexCodec一起使用，以使http / 2连接向后兼容ChannelHandler s期望HttpObject为简单起见，它将转换为分块编码，除非整个流为单个标头。

所有方法接口方法具体的方法
Modifier and Type	Method and Description
`boolean`	`acceptInboundMessage(java.lang.Object msg)` 当且仅当指定的消息可以被该编解码器解码时返回 `true` 。
`protected void`	`decode(ChannelHandlerContext ctx, Http2StreamFrame frame, java.util.List<java.lang.Object> out)`
`protected void`	`encode(ChannelHandlerContext ctx, HttpObject obj, java.util.List<java.lang.Object> out)` 编码从`HttpObject`到`Http2StreamFrame` 。
`void`	`handlerAdded(ChannelHandlerContext ctx)` 子类可以忽略这个方法。
