@ChannelHandler.Sharable public class Base64Encoder extends OneToOneEncoder
ChannelBuffer
into a Base64-encoded ChannelBuffer
.
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
());

, unlike
you can in OneToOneDecoder.decode(ChannelHandlerContext, Channel, Object)
;
you must return something, at least ChannelBuffers.EMPTY_BUFFER
.encode
in class OneToOneEncoder
