Languages that present containers considered heterogenous merely deliver containers of elements that all present a normal interface. One example is, Java collections supply containers of (references to) Objects and you employ the (typical) Item interface to find the real style of an element. The C++ standard library gives homogeneous containers due to the fact These are the easiest to employ while in the overwhelming majority of scenarios, gives the most beneficial compile-time mistake information, and imposes no unwanted run-time overheads. If you need a heterogeneous container in C++, define a standard interface for all The weather and come up with a container of All those. As an example: course Io_obj /* ... */ ; // the interface necessary To participate in object I/O vector vio; // if you want to deal with the ideas straight vector< Deal with > v2; // If you prefer a "smart pointer" to handle the objects You should not fall to the bottom volume of implementation depth unless You need to: vector memory; // rarely required A fantastic indicator that you've got "absent also lower degree" is that the code will get suffering from casts. Employing an Any course, for instance Raise::Any, is usually an alternate in certain courses: vector v; Why would be the typical containers so sluggish?
