| C++ associative containers are usually based on red-black tree implementations |
| (e.g.: STL, Boost.Intrusive associative containers). However, there are other |
| interesting data structures that offer some advantages (and also disadvantages). |
| </p> |
| <p> |
| Splay trees are self-adjusting binary search trees used typically in caches, |
| memory allocators and other applications, because splay trees have a "caching |
| effect": recently accessed elements have better access times than elements |
| accessed less frequently. For more information on splay trees see <a href="http://en.wikipedia.org/wiki/Splay_tree" target="_top">Wikipedia |
| entry</a>. |
| </p> |
| <p> |
| <span class="bold"><strong>Boost.Intrusive</strong></span> offers 3 containers based |
| on splay trees: <code class="computeroutput"><a class="link" href="../boost/intrusive/splay_set.html" title="Class template splay_set">splay_set</a></code>, |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/splay_multiset.html" title="Class template splay_multiset">splay_multiset</a></code> |
| and <code class="computeroutput"><a class="link" href="../boost/intrusive/splaytree.html" title="Class template splaytree">splaytree</a></code>. The |
| first two are similar to <code class="computeroutput"><a class="link" href="../boost/intrusive/set.html" title="Class template set">set</a></code> |
| or <code class="computeroutput"><a class="link" href="../boost/intrusive/multiset.html" title="Class template multiset">multiset</a></code> and the |
| latter is a generalization that offers functions both to insert unique and |
| multiple keys. |
| </p> |
| <p> |
| The memory overhead of these containers with Boost.Intrusive hooks is usually |
| 3 pointers. An empty, non constant-time size splay container has also a size |
| of 3 pointers. |
| </p> |

| and disadvantages of splay tree based containers</a> |
| </h3></div></div></div> |
| <p> |
| Splay tree based intrusive containers have logarithmic complexity in many |
| operations like searches, insertions, erasures, etc., but if some elements |
| are more frequently accessed than others, splay trees perform faster searches |
| than equivalent balanced binary trees (such as red-black trees). |
| </p> |
| <p> |
| The caching effect offered by splay trees comes with a cost: the tree must |
| be rebalanced when an element is searched. This disallows const versions |
| of search functions like <code class="computeroutput"><span class="identifier">find</span><span class="special">()</span></code>, <code class="computeroutput"><span class="identifier">lower_bound</span><span class="special">()</span></code>, <code class="computeroutput"><span class="identifier">upper_bound</span><span class="special">()</span></code>, <code class="computeroutput"><span class="identifier">equal_range</span><span class="special">()</span></code>, <code class="computeroutput"><span class="identifier">count</span><span class="special">()</span></code>, etc. |
| </p> |
| <p> |
| Because of this, splay-tree based associative containers are not drop-in |
| replacements of <code class="computeroutput"><a class="link" href="../boost/intrusive/set.html" title="Class template set">set</a></code>/ |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/multiset.html" title="Class template multiset">multiset</a></code>. |
| </p> |
| <p> |
| Apart from this, if element searches are randomized, the tree will be rebalanced |
| without taking advantage of the cache effect, so splay trees can offer worse |
| performance than other balanced trees for some search patterns. |
