It mean I must use an Array<A*> ? Their is no way to do something like the exemple bellow without having to work with ptr ?

Array<A> is similar to Vector<A*>.
The only difference is that it (Array<A>) owns data. This means that Array<A> in its destructor will call delete on each pointer it stores, so, you cannot store pointers to objects on stack in an Array.
