<a name="idp319055488"></a><h2>Description</h2>
<p>The class template <a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a> is an intrusive container, that mimics most of the interface of std::tr1::unordered_multiset as described in the C++ TR1.</p>
<p><a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a> is a semi-intrusive container: each object to be stored in the container must contain a proper hook, but the container also needs additional auxiliary memory to work: <a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a> needs a pointer to an array of type <code class="computeroutput">bucket_type</code> to be passed in the constructor. This bucket array must have at least the same lifetime as the container. This makes the use of <a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a> more complicated than purely intrusive containers. <code class="computeroutput">bucket_type</code> is default-constructible, copyable and assignable</p>
<p>The template parameter <code class="computeroutput">T</code> is the type to be managed by the container. The user can specify additional options and if no options are provided default options are used.</p>
<p>The container supports the following options: <code class="computeroutput">base_hook<>/member_hook<>/value_traits<></code>, <code class="computeroutput">constant_time_size<></code>, <code class="computeroutput">size_type<></code>, <code class="computeroutput">hash<></code> and <code class="computeroutput">equal<></code> <code class="computeroutput">bucket_traits<></code>, <code class="computeroutput">power_2_buckets<></code> and <code class="computeroutput">cache_begin<></code>.</p>
<p><a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a> only provides forward iterators but it provides 4 iterator types: iterator and const_iterator to navigate through the whole container and local_iterator and const_local_iterator to navigate through the values stored in a single bucket. Local iterators are faster and smaller.</p>
<p>It's not recommended to use non constant-time size unordered_multisets because several key functions, like "empty()", become non-constant time functions. Non constant-time size unordered_multisets are mainly provided to support auto-unlink hooks.</p>
<p><a class="link" href="unordered_multiset.html" title="Class template unordered_multiset">unordered_multiset</a>, unlike std::unordered_set, does not make automatic rehashings nor offers functions related to a load factor. Rehashing can be explicitly requested and the user must provide a new bucket array that will be used from that moment.</p>
<p>Since no automatic rehashing is done, iterators are never invalidated when inserting or erasing elements. Iterators are only invalidated when rehasing. </p>
