RE: [sv-ec] RE: [sv-cc] FW: a question about system verilog class deconstructor

Doug,

The Vera language does include a finalize method to address precisely the type of issue faced by Alex. Extending this to SV is straightforward. There are a few issues that need to be addressed such as: What is the process that calls the finalize method? When is a finalize method called? Are finalize methods called every time? And my favorite peeve: Does finalize support object resuscitation?

Joao,

What a great wikipedia reference.  Thanks!
This new information makes the issues a bit clearer to me.

One take on it would be:

a) For garbage collection and implicit control, go with the
   finalizer concept. Though, there are those limitations
   and bad properties mentioned in the WikiPedia entry.

b) For users who want to use an explicit control strategy,
   (i.e. call cleanup code and then assign to null),
   users could avoid declaring finalizer methods and go
   with explicit cleanup methods instead.

Regards,
Doug
