https://svn.boost.org/trac10/ticket/12763 <p> It would be convenient if there was a way to specify a default disposer to be applied to elements stored in an intrusive container. This would make it easier to write containers that take ownership of their inserted elements. </p> <p> This would impact the container's destructor as well as the methods <code>erase</code>, <code>erase_after</code>, <code>clear</code>, <code>remove</code>, <code>remove_if</code>, <code>pop_front</code>, <code>pop_back</code>, <code>assign</code>, <code>unique</code> and <code>clone_from</code>. </p> <p> The library should probably provide a no-op disposer, which would be the default one used by intrusive containers. Particular care should be taken in <code>clear</code> and containers' destructors in order to avoid calling the no-op disposer for every element. </p> <p> For example: </p> <pre class="wiki">boost::intrusive::list&lt;MyElement, boost::intrusive::disposer&lt;std::default_delete&lt;MyElement&gt;&gt;&gt; elems; elems.insert(*new MyElement); // Clearing the collection deletes the elements. elems.clear(); </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/12763 Trac 1.4.3 fdegros@… Mon, 27 Feb 2017 05:38:35 GMT
