size of objects estimation for Wicket

[Eelco Hillenius <ee...@gmail.com>]

Hi,

What do you think of this approach

object sizes opposed to doing it using serialization like we do now?

I just implemented a little pattern to delegate Objects.sizeOf to a
strategy. The idea behind that is that we could plugin Java 5 based
calculations with wicket 1.3 (which obviously only works when people
are on 1.5). For that, we could follow the approach as outlined here:

Any thoughts on how he does that?

Thats pretty much how serialization works now (with a byte counting
outputstream)
Except that serialization doesn't count transient fields (which ofcourse
also cost memory)
And you kill some overhead also by doing this.
