<p>Meets many of the requirements of a <a href="tables.html#65">container</a>, but does not define anything to do with iterators. Very few of the other standard container interfaces are defined.</p>
<p>This is not a true container, but an <em>adaptor</em>. It holds another container, and provides a wrapper interface to that container. The wrapper is what enforces strict first-in-last-out stack behavior.</p>
<p>The second template parameter defines the type of the underlying sequence/container. It defaults to std::deque, but it can be any type that supports <code>back</code>, <code>push_back</code>, and <code>pop_back</code>, such as std::list, std::vector, or an appropriate user-defined type.</p>
<p>Members not found in <em>normal</em> containers are <code>container_type</code>, which is a typedef for the second Sequence parameter, and <code>push</code>, <code>pop</code>, and <code>top</code>, which are standard stack/FILO operations. </p>
