io.netty.handler.codec.bytes.ByteArrayEncoder
- All Implemented Interfaces:
ChannelHandler
,ChannelOutboundHandler
Encodes the requested array of bytes into a
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) {
...
}

encode
Description copied from class:MessageToMessageEncoder
Encode from one message to an other. This method will be called for each written message that can be handled by this encoder.- Specified by:
encode
in classMessageToMessageEncoder<byte[]>
- Parameters:
ctx
- theChannelHandlerContext
which thisMessageToMessageEncoder
belongs tomsg
- the message to encode to an other oneout
- theList
into which the encoded msg should be added needs to do some kind of aggregation- Throws:
Exception
- is thrown if an error occurs
