所有已实现的接口:

ChannelHandler, ChannelInboundHandler, ChannelOutboundHandler

@UnstableApi
 @ChannelHandler.Sharable
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 Http2MultiplexCodec 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.

方法详细资料

acceptInboundMessage

public boolean acceptInboundMessage(java.lang.Object msg)
                             throws java.lang.Exception

从类复制的说明: MessageToMessageCodec

Returns true if and only if the specified message can be decoded by this codec.

覆盖:

acceptInboundMessage 在类中 MessageToMessageCodec<Http2StreamFrame,HttpObject>

参数:

msg - the message

抛出:

java.lang.Exception

decode

protected void decode(ChannelHandlerContext ctx,
                      Http2StreamFrame frame,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception

指定者:

decode 在类中 MessageToMessageCodec<Http2StreamFrame,HttpObject>

抛出:

java.lang.Exception

另请参阅:

MessageToMessageDecoder.decode(ChannelHandlerContext, Object, List)

encode

protected void encode(ChannelHandlerContext ctx,
                      HttpObject obj,
                      java.util.List<java.lang.Object> out)
               throws java.lang.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.

指定者:

encode 在类中 MessageToMessageCodec<Http2StreamFrame,HttpObject>

参数:

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

抛出:

java.lang.Exception - is thrown if an error occurs

另请参阅:

MessageToMessageEncoder.encode(ChannelHandlerContext, Object, List)

handlerAdded

public void handlerAdded(ChannelHandlerContext ctx)
                  throws java.lang.Exception

从类复制的说明: ChannelHandlerAdapter

Do nothing by default, sub-classes may override this method.

指定者:

handlerAdded 在接口中 ChannelHandler

覆盖:

handlerAdded 在类中 ChannelHandlerAdapter

抛出:

java.lang.Exception

isSsl

protected boolean isSsl(ChannelHandlerContext ctx)
