- - io.netty5.handler.codec.MessageToMessageCodec<Http2StreamFrame,HttpObject>
  - - io.netty5.handler.codec.http2.Http2StreamFrameToHttpObjectCodec

All Implemented Interfaces:

ChannelHandler
```
@UnstableApi
public class Http2StreamFrameToHttpObjectCodec
extends MessageToMessageCodec<Http2StreamFrame,HttpObject>
```
This handler converts from Http2StreamFrame to HttpObject, and back. It can be used as an adapter in conjunction with Http2MultiplexHandler to make http/2 connections backward-compatible with ChannelHandlers expecting HttpObject For simplicity, it converts to chunked encoding unless the entire stream is a single header.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`acceptInboundMessage(Object msg)`	Returns `true` if and only if the specified message can be decoded by this codec.
`protected void`	`decodeAndClose(ChannelHandlerContext ctx, Http2StreamFrame frame)`
`protected void`	`encodeAndClose(ChannelHandlerContext ctx, HttpObject obj, List<Object> out)`	Encode from an `HttpObject` to an `Http2StreamFrame`.
`void`	`handlerAdded(ChannelHandlerContext ctx)`	Gets called after the `ChannelHandler` was added to the actual context and it's ready to handle events.
`boolean`	`isSharable()`	Returns `true` if this handler is sharable and thus can be added to more than one `ChannelPipeline`.
`protected boolean`	`isSsl(ChannelHandlerContext ctx)`

  - isSharable
```
public boolean isSharable()
```
    Description copied from interface: ChannelHandler
    
    Returns true if this handler is sharable and thus can be added to more than one ChannelPipeline. By default, this method returns false. If this method returns false, you have to create a new handler instance every time you add it to a pipeline because it has unshared state such as member variables.
  - acceptInboundMessage
```
public boolean acceptInboundMessage(Object msg)
                             throws Exception
```
    Description copied from class: MessageToMessageCodec
    
    Returns true if and only if the specified message can be decoded by this codec.
    
    Overrides:
    
    acceptInboundMessage in class MessageToMessageCodec<Http2StreamFrame,HttpObject>
    
    Parameters:
    
    msg - the message
    
    Throws:
    
    Exception
  - decodeAndClose
```
protected void decodeAndClose(ChannelHandlerContext ctx,
                              Http2StreamFrame frame)
                       throws Exception
```
    Overrides:
    
    decodeAndClose in class MessageToMessageCodec<Http2StreamFrame,HttpObject>
    
    Throws:
    
    Exception

  - encodeAndClose
```
protected void encodeAndClose(ChannelHandlerContext ctx,
                              HttpObject obj,
                              List<Object> out)
                       throws Exception
```
    Encode from an HttpObject to an Http2StreamFrame. This method will be called for each written message that can be handled by this encoder. NOTE: 100-Continue responses that are NOT FullHttpResponse will be rejected.
    
    Overrides:
    
    encodeAndClose in class MessageToMessageCodec<Http2StreamFrame,HttpObject>
    
    Parameters:
    
    ctx - the ChannelHandlerContext which this handler belongs to
    
    obj - the HttpObject message to encode
    
    out - the List into which the encoded msg should be added needs to do some kind of aggregation
    
    Throws:
    
    Exception - is thrown if an error occurs
    
    See Also:
    
    MessageToMessageEncoder.encodeAndClose(ChannelHandlerContext, Object, List)
  - handlerAdded
```
public void handlerAdded(ChannelHandlerContext ctx)
                  throws Exception
```
    Description copied from interface: ChannelHandler
    
    Gets called after the ChannelHandler was added to the actual context and it's ready to handle events.
    
    Throws:
    
    Exception
  - isSsl

protected boolean isSsl(ChannelHandlerContext ctx)
