+<h2>Introduction</h2>\r
+\r
+<p><code>sorted_vector</code> adapts a <code>std::vector</code> to the interface required by\r
+<code>std::set/std::multiset</code>, thereby providing set/multiset and vector\r
+functionality (random access) in one container.</p>\r
+\r
+<p>Tests show that <code>sorted_vector</code>'s element retrieval (find) speed outperforms\r
+that of <code>std::set/std::multiset</code> by a factor of 2 (on most machines). On the downward side is \r
+the poor performance of <code>sorted_vector</code>'s insert member function, because it\r
+inserts an element somewhere in the middle of the sorted vector in order\r
+to preserve the sort order. By using <code>sorted_vector</code>'s low level interface one can\r
+solve this performance bottleneck by inserting a bunch of objects using a series of \r
+<code>push_back</code>'s followed by a call to the member function <code>sort</code>, which restores the sort\r
+order. </p>\r
+\r
+<p><code>sorted_vector</code> should be preferred over <code>std::set/std::multiset</code> \r
+if many small elements\r
+must be stored. Most STL implementations use a variant of a balanced tree to \r
+implement set and multiset, which imposes a per element storage overhead of 3 pointers.\r
+The most important reason to use a <code>std::set/std::multiset</code> instead of \r
+<code>sorted_vector</code> is\r
+the need to keep iterators into a set/multiset while inserting more elements into\r
+the set. These iterators remain valid in the case of a set/multiset, but are invalidated\r
+in the case of a <code>sorted_vector</code> container. </p>\r
+\r
+<h2>Namespace</h2>\r
+<p><code>sorted_vector</code> resides in the namespace <code>codeproject</code>.</p>\r
+\r
+<h2>Basic Usage</h2>\r
+\r
+<p>The following small table shows corresponding declarations of <code>sorted_vector</code>'s \r
+and <code>set</code>'s/<code>multiset</code>'s.</p>\r

+<TD VAlign=top><code>sorted_vector<Key,Pred></code></TD>\r

+\r
+<p>(<code>sorted_vector<Key,Pred,<span class='cpp-keyword'>true</span>></code> means <code>sorted_vector<Key,Pred,bNoDuplicates=<span class='cpp-keyword'>true</span>></code>)</p>\r
+\r
+<P>The various set/multiset <code>insert</code> and <code>erase</code> member functions as well as the\r
+set/multiset functions <code>count, lower_bound,upper_bound, equal_range</code> are part of \r
+<code>sorted_vector</code>'s interface and behave the same as there set/multiset counterparts.\r
+The following code snippet shows the use of a <code>sorted_vector</code> to hold the\r
+set intersection of the content of two <code>std::vector</code>'s.</p>\r

+ svecIntersection.insert(v1[i]);\r
+ }\r
+ }\r
+ <span class="code-keyword">return</span> svecIntersection.size();\r
+}\r
+</pre>\r
+\r
+<p>The code example shows the use of the member functions <code>find</code> and <code>insert</code>. \r
+If you replace <code>codeproject::sorted_vector<<span class='cpp-keyword'>int</span>,<span class='cpp-keyword'>true</span>></code> by <code>std::set<<span class='cpp-keyword'>int</span>></code> you get exactly\r
+the same result. This piece of code can be optimized for speed by replacing the insert calls in the loop \r
+by calls to <code>push_back</code> of the base container (a vector) followed by a call \r
+to the member function <code>sort</code> at the end of the loop.</p>\r

+<h2>Points of Interest</h2>\r
+\r
+<p>An interview with Alexander Stepanov (inventor of the STL) at\r
+<A href="http://www.stlport.org/resources/StepanovUSA.html">http://www.stlport.org/resources/StepanovUSA.html</A>\r
+, in which he proposed to implement\r
+a sorted container as an adapter of a <code>std::container</code> gave me the idea for this work.\r
+The real surprise to me was the unexpected good performance of <code>sorted_vector</code> compared\r
+to set/multiset. The outcome of my tests indicate, that the <code>std::set/std::multiset</code>\r
+has only one (important) advantage over a sorted vector, namely that iterators remain\r
+valid in a set/multiset, even when more elements are added.\r
+</p>\r
+\r
+<p>The implementation work itself was easy and did not require any advanced C++/STL feature.\r
+It can be summarized as follows:\r
+Most of the member functions of <code>sorted_vector</code> forward the call to the <code>vec_</code> data member,\r
+which is a <code>std::vector</code>. The set/multiset specific functions for inserting/erasing and\r
+locating elements mostly use STL algorithms to deal with the sorted sequence present\r
+in the <code>vec_</code> data member. The low level interface consisting of the member functions\r
+ <code>get_container()</code> (which returns a reference to the <code>vec_</code> data member) \r
+and <code>sort</code> and <code>stable_sort</code> \r
+ (which restore the sort order) are necessary to improve insertion performance (by allowing\r
+ a temporary violation of the sorting order).\r
+Only one function was unexpectedly difficult to implement: The function <code>unique</code>, which\r
+must be called after <code>sort</code> and <code>stable_sort</code> in the case of a set. \r
+This function is part of the STL and requires a predicate as third argument. This predicate must return true,\r
+if the passed elements are equal. But the class <code>sorted_vector</code> only has access to a predicate\r
+which evaluates the < relation. In theory, it should be possible, to transform a predicate\r
+evaluating the < relation into another predicate evaluating ==, but in practice this is only\r
+possible, when the < predicate is implemented as object derived from <code>std::binary_function</code>.\r
+Ultimately, I had to implement <code>unique</code> myself because of that. </p>\r
