org.jboss.netty.handler.codec.replay.ReplayingDecoder<HttpMessageDecoder.State>
org.jboss.netty.handler.codec.http.HttpMessageDecoder
org.jboss.netty.handler.codec.rtsp.RtspMessageDecoder
- All Implemented Interfaces:
ChannelHandler
,ChannelUpstreamHandler
,LifeCycleAwareChannelHandler
- Direct Known Subclasses:
RtspRequestDecoder
,RtspResponseDecoder
Decodes
ChannelBuffer
s into RTSP messages represented in
HttpMessage
s.
Parameters that prevents excessive memory consumption
Name | Meaning |
---|---|
maxInitialLineLength |
The maximum length of the initial line
(e.g. "SETUP / RTSP/1.0" or "RTSP/1.0 200 OK" )
If the length of the initial line exceeds this value, a
TooLongFrameException will be raised. |
maxHeaderSize |
The maximum length of all headers. If the sum of the length of each
header exceeds this value, a TooLongFrameException will be raised. |
maxContentLength |
The maximum length of the content. If the content length exceeds this
value, a TooLongFrameException will be raised. |

decode
protected Object decode(ChannelHandlerContext ctx, Channel channel, ChannelBuffer buffer, HttpMessageDecoder.State state) throws Exception Description copied from class:ReplayingDecoder
Decodes the received packets so far into a frame.- Overrides:
decode
in classHttpMessageDecoder
- Parameters:
ctx
- the context of this handlerchannel
- the current channelbuffer
- the cumulative buffer of received packets so far. Note that the buffer might be empty, which means you should not make an assumption that the buffer contains at least one byte in your decoder implementation.state
- the current decoder state (null
if unused)- Returns:
- the decoded frame
- Throws:
Exception
