Tell us what you think about keeping functors and functions together in an array, as featured in our Aug. 7, 2002 C++ newsletter. How have functors and functions been useful to you?

Alas, the technique described in this C++ tip demonstrates one way of not solving this problem :-( It is at best half the solution, but it fails to finish the job, leaving memory management unencapsulated, exposing the user to far, far more complexity than they need.

The final solution can -- and should -- be simpler in implementation and easier to use. For the relevant techniques, have a look at my CUJ online article from November 2000, "Function Follows Form":

Hi Kevlin,

Thanks for your feedback.
You are partially correct. It was sloppy of me to leave out memory management.

However, should have I included that, I guess the code would have become more complicated.

In a future tip, I will show a way to be able to keep pointers in a container, and manage memory management (destruction) internally.

John
