public class ByteArrayDecoder extends MessageToMessageDecoder<ByteBuf>
ByteBuf
into an array of bytes.
A typical setup for TCP/IP would be:
and then you can use an array of bytes instead of aChannelPipeline
pipeline = ...; // Decoders pipeline.addLast("frameDecoder", newLengthFieldBasedFrameDecoder
(1048576, 0, 4, 0, 4)); pipeline.addLast("bytesDecoder", newByteArrayDecoder
()); // Encoder pipeline.addLast("frameEncoder", newLengthFieldPrepender
(4)); pipeline.addLast("bytesEncoder", newByteArrayEncoder
());
ByteBuf
as a message:
void channelRead(ChannelHandlerContext
ctx, byte[] bytes) {
...
}
