<h2 class="subtitle" id="insert-iterators">Insert Iterators</h2>
<p>When you work with normal value-based containers and algorithms, you often
use insert iterators</p>
<pre class="literal-block">
std::list<int> coll1;
// ...
std::vector<int> coll2;
std::copy( coll1.begin(), coll1.end(),
back_inserter(coll2) );
</pre>
<p>With the special insert iterators for pointer containers,
you can do exactly the same</p>
<pre class="literal-block">
boost::ptr_list<Base> coll1;
// ...
boost::ptr_vector<Base> coll2;
std::copy( coll1.begin(), coll1.end(),
boost::ptr_container::ptr_back_inserter(coll2) );
</pre>
<p>Each element is cloned and inserted into the container. Furthermore,
if the source range iterates over pointers
instead of references, <tt class="docutils literal"><span class="pre">NULL</span></tt> pointers
can be transfered as well.</p>
