| <span class="bold"><strong>Boost.Intrusive</strong></span> also offers associative containers |
| that can be very useful when creating more complex associative containers, |
| like containers maintaining one or more indices with different sorting semantics. |
| Boost.Intrusive associative containers, like most STL associative container |
| implementations are based on red-black trees. |
| </p> |
| <p> |
| The memory overhead of these containers is usually 3 pointers and a bit (with |
| alignment issues, this means 3 pointers and an integer). This size can be reduced |
| to 3 pointers if pointers have even alignment (which is usually true in most |
| systems). |
| </p> |
| <p> |
| An empty, non constant-time size <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> or <code class="computeroutput"><a class="link" href="../boost/intrusive/rbtree.html" title="Class template rbtree">rbtree</a></code> has also the size of 3 pointers |
| and an integer (3 pointers when optimized for size). These containers have |
| logarithmic complexity in many operations like searches, insertions, erasures, |
| etc. <code class="computeroutput"><a class="link" href="../boost/intrusive/set.html" title="Class template set">set</a></code> and <code class="computeroutput"><a class="link" href="../boost/intrusive/multiset.html" title="Class template multiset">multiset</a></code> are the intrusive equivalents |

| containers. |

| <p> |
| <code class="computeroutput"><a class="link" href="../boost/intrusive/rbtree.html" title="Class template rbtree">rbtree</a></code> is a superset |
