| <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> |
