Languages that give containers considered heterogenous merely offer containers of components that each one give a standard interface. For example, Java collections deliver containers of (references to) Objects and you utilize the (typical) Object interface to find out the true kind of a component. The C++ normal library supplies homogeneous containers since Individuals are the easiest to implement from the overwhelming majority of cases, presents the best compile-time error concept, and imposes no unwanted operate-time overheads. If you want a heterogeneous container in C++, define a standard interface for all The weather and create a container of People. One example is: course Io_obj /* ... */ ; // the interface desired To participate in item I/O vector vio; // if you'd like to deal with the ideas specifically vector< Manage > v2; // If you would like a "good pointer" to take care of the objects Don't drop to the bottom level of implementation depth Until You need to: vector memory; // rarely necessary A great sign that you've "long gone too very low stage" is that the code gets littered with casts. Making use of an Any course, which include Improve::Any, is often an alternative in certain plans: vector v; Why are definitely the conventional containers so sluggish?
