Re: Getting size of a class

[Curt Smith <chsmith@speakeasy.net>]

One technique that I've seen, since there is no direct method is to 
serialize
the object and then check the size of the resultant array, String etc. 
 I've heard
this is not inexpensive.

If you do this only for development metrics you might not care about 
expense.
A simple way since these will be your classes, is to implement 
Externalizable and
then to put you more efficient writeExternal() method that will just 
count the bytes
vs really go through the effort of writting to the outputStream.

Good luck,  curt
