All Implemented Interfaces:
CodecEmbedder<E>
public class DecoderEmbedder<E> extends AbstractCodecEmbedder<E>
A helper that wraps a decoder so that it can be used without doing actual I/O in unit tests or higher level codecs. For example, you can decode a Base64-encoded ChannelBuffer with Base64Decoder and StringDecoder without setting up the ChannelPipeline and other mock objects by yourself: 
 ChannelBuffer base64Data = ChannelBuffers.copiedBuffer("Zm9vYmFy", CharsetUtil.US_ASCII);

 DecoderEmbedder<String> embedder = new DecoderEmbedder<String>(
         new Base64Decoder(), new StringDecoder());

 embedder.offer(base64Data);

 String decoded = embedder.poll();
 assert decoded.equals("foobar");
