 Posted: Wed Dec 20, 2006 10:10 am Post subject: Question about virtual |
 |
|
I have two classes. One with a regular destructor and the other with a
virtual destructor.
e.g.
class x {
~x(){}
}
vs
class y {
virtual ~x{}
}
Question:
1. is y likely to use more memory?
2. is the construct y likely to be slower?
as i understand, it is less efficient when calling y...but i m not sure
about the memory and construction..
Thanks! |

Premature optimization (or pessimization) is evil.
Measure.
Then don't do it.
