A container is an STL template class that manages a sequence of elements. Such elements can be of any object type that supplies a default constructor, a destructor, and an assignment operator. This document describes the properties required of all such containers, in terms of a generic template class Cont. An actual container template class may have additional template parameters. It will certainly have additional member functions.

The STL template container classes are:

    deque
    list
    map
    multimap
    multiset
    set
    vector

(The Standard C++ library template class basic_string also meets the requirements for a template container class.)
