Languages that give containers deemed heterogenous merely give containers of features that every one provide a normal interface. As an example, Java collections offer containers of (references to) Objects and you use the (widespread) Object interface to discover the true style of an element. The C++ standard library gives homogeneous containers for the reason that Individuals are the best to make use of in the vast majority of cases, gives the top compile-time error information, and imposes no unwanted run-time overheads. If you want a heterogeneous container in C++, determine a typical interface for all The weather and produce a container of These. For instance: course Io_obj /* ... */ ; // the interface required To participate in item I/O vector vio; // if you'd like to handle the tips instantly vector< Deal with > v2; // If you prefer a "intelligent pointer" to deal with the objects Will not drop to the lowest amount of implementation depth Except You need to: vector memory; // hardly ever wanted A good indication that you've "absent too reduced degree" is that the code receives suffering from casts. Using an Any course, including Boost::Any, is usually an alternative in some systems: vector v; Why are the conventional containers so sluggish?
