    copied!<p>I've got a function inside a class (A) that essentially takes as a parameter a pointer to another class (B). The B class is inherited by multiple other classes which it should also accept.</p> <p>What I would like to do is take ownership of this pointer to store for later use in the class, it won't be used outside the class again for anything else. While I would make the parameter a shared_ptr, I would like to avoid that as much as possible due to other people I work with who don't quite get the whole smart pointer thing. Is there any way to do this? </p> <p>Here's a sort of example that I would like to do, although from what I've tested this doesn't work.</p> <pre><code>//In .h file std::vector&lt; unique_ptr&lt; B &gt; &gt; data_store; //In .cpp file void A::add_data(B* NewItem) { data_store.resize(data_store.size()+1); data_store[data_store.size()-1] = NewItem; } </code></pre> <p>Second to that, I would like to maybe use a copy constructor or something similar to use a smart pointer inside the class: with what I'm having to do it could get a bit ugly if I have to do manual deletes. The problem with that is that I don't know whether it's the base class (B) coming in or whether it's a class that inherited from B. I'm not too sure how to deal with that without having to hard-code in some kind of checkable ID for the class and using the correct copy/move constructors, which I would like to avoid at all costs.</p> <p>I'm using an updated Clang and libC++ from llvm which I updated about 10am UK time on 12th March 2012.</p>
