本文整理了Java中org.jboss.netty.handler.codec.compression.ZlibDecoder类的一些代码示例，展示了ZlibDecoder类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZlibDecoder类的具体详情如下：
包路径：org.jboss.netty.handler.codec.compression.ZlibDecoder
类名称：ZlibDecoder

ZlibDecoder介绍

[英]Decompresses a ChannelBuffer using the deflate algorithm.
[中]使用deflate算法解压缩ChannelBuffer。

代码示例

代码示例来源：origin: io.netty/netty

@Override
  protected DecoderEmbedder<ChannelBuffer> newContentDecoder(String contentEncoding) throws Exception {
    if ("gzip".equalsIgnoreCase(contentEncoding) || "x-gzip".equalsIgnoreCase(contentEncoding)) {
      return new DecoderEmbedder<ChannelBuffer>(new ZlibDecoder(ZlibWrapper.GZIP));
    }
    if ("deflate".equalsIgnoreCase(contentEncoding) || "x-deflate".equalsIgnoreCase(contentEncoding)) {
      // To be strict, 'deflate' means ZLIB, but some servers were not implemented correctly.
      return new DecoderEmbedder<ChannelBuffer>(new ZlibDecoder(ZlibWrapper.ZLIB_OR_NONE));
    }

    // 'identity' or unsupported
    return null;
  }
}

ZlibEncoder encoder = new ZlibEncoder(compressionLevel);
pipeline.addFirst("deflater", encoder);
pipeline.addFirst("inflater", new ZlibDecoder());

  }

   logger.info("SSLEngine protocols enabled: " +
     Arrays.asList(sslEngine.getEnabledProtocols()));
   // addFirst() will make SSL handling the first stage of decoding
   // and the last stage of encoding this must be added after
   // adding compression handling above
   pipeline.addFirst("ssl", new SslHandler(sslEngine));
  });
