Class Base64Decoder
- java.lang.Object
-
- org.jboss.netty.handler.codec.oneone.OneToOneDecoder
-
- org.jboss.netty.handler.codec.base64.Base64Decoder
-
- All Implemented Interfaces:
ChannelHandler
,ChannelUpstreamHandler
@Sharable public class Base64Decoder extends OneToOneDecoder
Decodes a Base64-encodedChannelBuffer
or US-ASCIIString
into aChannelBuffer
. Please note that this decoder must be used with a properFrameDecoder
such asDelimiterBasedFrameDecoder
if you are using a stream-based transport such as TCP/IP. A typical decoder 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
());
