Class HttpContentDecoder

java.lang.Object
org.jboss.netty.channel.SimpleChannelUpstreamHandler
org.jboss.netty.handler.codec.http.HttpContentDecoder
All Implemented Interfaces:
ChannelHandler, ChannelUpstreamHandler, LifeCycleAwareChannelHandler
Direct Known Subclasses:
HttpContentDecompressor
public abstract class HttpContentDecoder extends SimpleChannelUpstreamHandler implements LifeCycleAwareChannelHandler
Decodes the content of the received HttpRequest and HttpChunk. The original content is replaced with the new content decoded by the DecoderEmbedder, which is created by newContentDecoder(String). Once decoding is finished, the value of the 'Content-Encoding' header is set to the target content encoding, as returned by getTargetContentEncoding(String). Also, the 'Content-Length' header is updated to the length of the decoded content. If the content encoding of the original is not supported by the decoder, newContentDecoder(String) should return null so that no decoding occurs (i.e. pass-through).

Please note that this is an abstract class. You have to extend this class and implement newContentDecoder(String) properly to make this class functional. For example, refer to the source code of HttpContentDecompressor.

This handler must be placed after HttpMessageDecoder in the pipeline so that this handler can intercept HTTP requests after HttpMessageDecoder converts ChannelBuffers into HTTP requests.
