Can netty codec send package while object serialization

Question

suppose I want to use netty 4.X to transfer big java object (with many container). I want to use a ByteBuf as buffer during encoder in order to optimize performance and minimize memory usage, so I have two questions before I proceed.

1- I want to use MessageToByteEncoder to complete this job, is it suitable?

2- Can we writeAndFlush ByteBuf to ChannelHandlerContext when ever buffer's capacity is reached inside encod(ChannelHandlerContext, Object, ByteBuf)?

Answer 1

从您的问题来看，您似乎想使用ChannelOutboundHandlerAdaptor并且只要填充缓冲区就可以在write(...)和ctx.write(...)调用中ctx.write(...)分配ByteBuf。
