Languages that present containers considered heterogenous basically deliver containers of components that each one supply an ordinary interface. Such as, Java collections offer containers of (references to) Objects and you utilize the (widespread) Object interface to discover the true form of an element. The C++ typical library provides homogeneous containers because These are the best to make use of during the vast majority of circumstances, provides the top compile-time mistake message, and imposes no needless run-time overheads. If you want a heterogeneous container in C++, outline a common interface for all The weather and generate a container of These. By way of example: class Io_obj /* ... */ ; // the interface needed to take part in item I/O vector vio; // if you'd like to handle the tips immediately vector< Cope with > v2; // if you want a "smart pointer" to deal with the objects Will not fall to the lowest standard of implementation depth unless You should: vector memory; // rarely necessary An excellent indication that you've got "gone also very low stage" is that the code will get suffering from casts. Using an Any class, which include Boost::Any, is usually an alternate in some programs: vector v; Why would be the normal containers so gradual?
