public static class NettyDecoder2 extends ByteToMessageDecoder{
@Override
protected void decode(ChannelHandlerContext ctx, ByteBuf in, List<Object>
out) throws Exception {
if((in.readableBytes() < 1119) ) {
return;
}
String msg = in.toString(CharsetUtil.UTF_8);
in.readerIndex(in.readerIndex() + in.readableBytes());
out.add(msg);
}
}
i create this code. but is there any way to know in.readableBytes() ?
it is very dynamic data. so i could not know the size.. give me a tip pz.
