What peoples thinks?
I asked some time ago about this thing
http://www.nabble.com/Question-about-http-on-grizzly-tt16846432.html - i
implemented this server (without grizzly, just plain NIO) and i use a simple
hashtable for storing connection related info in it. selectionkey is used as
a key and special class with connection info as a value in hashtable. why
not to implement it like this? i do not use selectionkey attachment bacause
of your blog :) - i agree that there are those disadvantages that you
pointed out. unneded entries from hashtable are removed whenever i close a
channel. also it is rather convenient to iterate throught connections.
My concern with using a Hashtable is that it forces a
Hashtable lookup on every read event. An attachment effectively
just puts the data in a place known the NIO so that it can be
returned directly, avoiding the lookup overhead.
Thanks,
