| <a name="id1983020"></a><h2>Description</h2> |
| <p>The class template unordered_multiset is an intrusive container, that mimics most of the interface of std::tr1::unordered_multiset as described in the C++ TR1.</p> |
| <p>unordered_multiset 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: unordered_multiset needs a pointer to an array of type `bucket_type` to be passed in the constructor. This bucket array must have at least the same lifetime as the container. This makes the use of unordered_multiset more complicated than purely intrusive containers. `bucket_type` 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>, power_2_buckets<> and cache_begin<>.</p> |
| <p>unordered_multiset 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>unordered_multiset, 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> |
