 150 <p>
 151           An unordered_[multi]set_of set view is a tr1::unordered[multi]set signature
 152           compatible interface to the underlying heap of elements contained in a
 153           <code class="computeroutput"><span class="identifier">bimap</span></code>.
 154         </p>
 155 <p>
 156           The interface and semantics of <code class="computeroutput"><span class="identifier">unordered_</span><span class="special">[</span><span class="identifier">multi</span><span class="special">]</span><span class="identifier">set_of</span></code>
 157           views are modeled according to the proposal for unordered associative containers
 158           given in the <a href="http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1836.pdf" target="_top">C++
 159           Standard Library Technical Report</a>, also known as TR1. An <code class="computeroutput"><span class="identifier">unordered_</span><span class="special">[</span><span class="identifier">multi</span><span class="special">]</span><span class="identifier">set_of</span></code> view is particularized according
 160           to a given <code class="computeroutput"><span class="identifier">Hash</span></code> function
 161           object which returns hash values for the keys and a binary predicate <code class="computeroutput"><span class="identifier">Pred</span></code> acting as an equivalence relation
 162           on values of Key.
 163         </p>
 164 <p>
 165           There are two variants: unordered_set_of, which do not allow duplicate
 166           elements (with respect to its associated comparison predicate) and unordered_multiset_of,
 167           which accept those duplicates. The interface of these two variants is the
 168           same to a great extent, so they are documented together with their differences
 169           explicitly noted when they exist.
 170         </p>
 171 <p>
 172           If you look the bimap by a side, you will use a map view and if you looked
 173           it as a whole you will be using a set view.
 174         </p>
 175 <p>
 176           Except where noted, <code class="computeroutput"><span class="identifier">unordered_</span><span class="special">[</span><span class="identifier">multi</span><span class="special">]</span><span class="identifier">set_of</span></code>
 177           views (both unique and non-unique) are models of <code class="literal">Unordered Associative
 178           Container</code>. Validity of iterators and references to elements is
 179           preserved in all cases. Occasionally, the exception safety guarantees provided
 180           are actually stronger than required by the extension draft. We only provide
 181           descriptions of those types and operations that are either not present
 182           in the concepts modeled or do not exactly conform to the requirements for
 183           unordered associative containers.
