@ChannelPipelineCoverage(value="all") public class StringDecoder extends OneToOneDecoder
ChannelBuffer into a String. Please
note that this decoder must be used with a proper FrameDecoder
such as DelimiterBasedFrameDecoder if you are using a stream-based
transport such as TCP/IP. A typical setup for a text-based line protocol
in a TCP/IP socket would be:
and then you can use aChannelPipelinepipeline = ...; // Decoders pipeline.addLast("frameDecoder", newDelimiterBasedFrameDecoder(80,Delimiters.lineDelimiter())); pipeline.addLast("stringDecoder", newStringDecoder("UTF-8")); // Encoder pipeline.addLast("stringEncoder", newStringEncoder("UTF-8"));
String instead of a ChannelBuffer
as a message:
void messageReceived(ChannelHandlerContext ctx, MessageEvent e) {
String msg = (String) e.getMessage();
ch.write("Did you say '" + msg + "'?\n");
}
