/**
 * Decodes a received {@link ByteBuf} into an array of bytes.
 * A typical setup for TCP/IP would be:
 *  * {@link ChannelPipeline} pipeline = ...;
 *
 * // Decoders
 * pipeline.addLast("frameDecoder",
 *                  new {@link LengthFieldBasedFrameDecoder}(1048576, 0, 4, 0, 4));
 * pipeline.addLast("bytesDecoder",
 *                  new {@link ByteArrayDecoder}());
 *
 * // Encoder
 * pipeline.addLast("frameEncoder", new {@link LengthFieldPrepender}(4));
 * pipeline.addLast("bytesEncoder", new {@link ByteArrayEncoder}());
 * 
 * and then you can use an array of bytes instead of a {@link ByteBuf}
 * as a message:
 *  * void channelRead({@link ChannelHandlerContext} ctx, byte[] bytes) {
 *     ...
 * }
