The selector <tt class="docutils literal"><span class="pre">vecS</span></tt>, for instance, indicates storage in a <tt class="docutils literal"><span class="pre">std::vector</span></tt> whereas <tt class="docutils literal"><span class="pre">listS</span></tt> indicates storage in a <tt class="docutils literal"><span class="pre">std::list</span></tt>. The Parallel BGL's <a class="reference external" href="distributed_adjacency_list.html">distributed adjacency list</a> supports an additional selector, <tt class="docutils literal"><span class="pre">distributedS</span></tt>, that indicates that the storage should be distributed across multiple processes.
