Data dispatching using dynamic_cast. How to avoid it?

[D. Susman]

Hi,

I am working on a data centric project. I have a Process function that
will be called by some thread. The signature goes:

void Process( Base* base )
{
}

There are hundred possibilities on what "base" actually (i.e. actual
run-time type) is. I would like to avoid the bulky if statements to
handle the downcasts. Is there a common approach/idiom to handle that?

Thank you.
