<p>This class is the combination of std::multiset and hash_multiset. </p>
<p>By setting database handles of DB_BTREE or DB_HASH type respectively, you will be using the equivalent of std::multiset or hash_multiset respectively. This container stores the key in the key element of a key/data pair in the underlying database, but doesn't store anything in the data element. Database and environment handle requirement: The requirement to these handles is the same as that to <a class="link" href="db_multimap.html" title="Chapter 6. Db_multimap">db_multimap</a>
