Hi All,<div><br></div><div>I have a number of named objects of type B whose name can be accessed by B::Name(). B is polymorphic. D1, D2 and so on are derived from B. I want to put them in a set or map-like container ordered by their names. They are referenced by other objects, such as of type C. If the objects in the container are changed by its type (from type D1 to D2) or value, their users can know it automatically, i.e. those information is shared among owners and users. To erase an object in the container, first we need to ensure it is not be used by other objects.</div>
<div><br></div><div>Please help me on choose a proper container with smart pointers. I am struggling with it by trying multi-index-container, pointer container, standard container, and cannot find a good way.</div><div><br>
</div><div>Thanks a lot ! !</div><div><br></div><div>Best regards,</div><div><br></div><div>Jayden</div>
