I have a doubt about how to keep a class... probably it is extremely simple to solve
This is the story:
- A class (A) has to keep a copy of other class (B)
- A can keep:
-- Case 1. a pointer to an instance of B created with new() by A
-- Case 2. a pointer to an instance of B handled in other place
- When A is destroyed
-- Case 1. B is destroyed in A destructor with a delete
-- Case 2. B is not destroyed. The owner has to destroy it
The problem of Case 2 it is that it is possible that B owner destroys B before A is destroyed... so if A is used in between, it can cause problems.
