@ChannelHandler.Sharable public class ByteArrayEncoder extends MessageToMessageEncoder<byte[]>
ByteBuf
.
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) {
...
}

MessageToMessageEncoder
encode
在类中 MessageToMessageEncoder<byte[]>
ctx
- the ChannelHandlerContext
which this MessageToMessageEncoder
belongs tomsg
- the message to encode to an other oneout
- the List
into which the encoded msg should be added
needs to do some kind of aggregationjava.lang.Exception
- is thrown if an error occurs
