@Sharable public class Base64Encoder extends MessageToMessageEncoder<ByteBuf>
Encodes aByteBuf
into a Base64-encodedByteBuf
. A typical setup for TCP/IP would be:ChannelPipeline
pipeline = ...; // Decoders pipeline.addLast("frameDecoder", newDelimiterBasedFrameDecoder
(80,Delimiters.nulDelimiter()
)); pipeline.addLast("base64Decoder", newBase64Decoder
()); // Encoder pipeline.addLast("base64Encoder", newBase64Encoder
());
