I noticed that the ctx is different from handler to handler even these handlers are in the same pipeline, for example
p.addLast("myHandler1", new MyHandler1());
p.addLast("myHandler2", new MyHandler2());
in MyHander1
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
System.err.println("My 1 ctx: " + ctx + " channel: " + ctx.channel());
super.channelRead(ctx, msg);
}
in MyHandler2
@Override
protected void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
System.err.println("My 2 ctx: " + ctx + " channel: " + ctx.channel());
}
and the output:
My 1 ctx: io.netty.channel.DefaultChannelHandlerContext@ba9340 channel: [id: 0xdfad3a16, /127.0.0.1:60887 => /127.0.0.1:8090]
My 2 ctx: io.netty.channel.DefaultChannelHandlerContext@1551d7f channel: [id: 0xdfad3a16, /127.0.0.1:60887 => /127.0.0.1:8090]
I noticed that the ctx is different but the channel is the same one
So it there any difference between invoke ctx.write() and ctx.channel().write() ?
