Writing a destructor is possible ?

Guillaume Nargeot

3/1/2007 1:59:00 AM

I would like to know if it is possible to write (for a class) something like
a destructor (like you do with C++), or something equivalent.
If it is not possible, how can I do to perform some operations on the
deletion of my object ?

Please look in the archives; this was just discussed last week.

In short, you can write a finalizer, but you'll never use it because
it may not be called. If you must release resources when your object
is destroyed, ensure that you provide a block form (like File.open).

Sorry, but I don't know were to find these archives... I thought I found
them on the internet, but I didn't find anything into them by searching
for "destructor" or "finalizer". Even by filtering this newsgroup topics
with these words I can't find anything since the 2007-02-16.

Can you tell me where I can find this discussion please ?
