[snipped]
yes, but this is no ordinary std::vector. std::vector is for self-contained value types; boost::ptr_vector is for pointers whose life-time must be managed.
| boost::vector<A> vector1, vector2; | vector1 = vector2;
boost::ptr_vector don't have an assignment operator; it is not Assignable nor CopyConstructible.
you must clone or release the container:
vector1 = vector2.clone(); vector1 = vector2.release();
I see, but it makes impossible for use ptr_containers inside other containers. Isnt this too restrictive? Cant they be implemented in terms of these? There were a discussion about this before? So that I can know the reasons why? what I was think is that the copy constructor and the assignment operator could be part of the clone policy. Maybe Im wrong.
