class foonathan::memory::allocator_polymorphic_deallocator&lt; BaseType, RawAllocator &gt;</h3>

<p>A deleter class that deallocates the memory of a derived type through a specified <a href="md_doc_concepts.html#concept_rawallocator">RawAllocator</a>. </p>
<p>It can only be created from a <a class="el" href="classfoonathan_1_1memory_1_1allocator__deallocator.html">allocator_deallocator</a> and thus must only be used for smart pointers initialized by derived-to-base conversion of the pointer. </p>
