<p>The class template <code>std::basic_stringstream</code> implements input/output operations on memory (<span class="t-lc"><a href="../string/basic_string.html" title="cpp/string/basic string">std::basic_string</a></span>) based streams. It essentially wraps a raw string device implementation (<span class="t-lc"><a href="basic_stringbuf.html" title="cpp/io/basic stringbuf">std::basic_stringbuf</a></span>) into a higher-level interface (<span class="t-lc"><a href="basic_iostream.html" title="cpp/io/basic iostream">std::basic_iostream</a></span>). The complete interface to unique <code>std::basic_stringbuf</code> members is provided.
