<h3>template<class T><br>
class Loki::FunctionStorage< T ></h3>
Implementation of the StoragePolicy used by <a class="el" href="a00132.html">SmartPtr</a>.
<p>
This storage policy is used by <a class="el" href="a00131.html" title="Encapsulate the object in a SmartPtr with FunctionStorage policy.">SmartPointer</a> CachedFactory's encapsulation policy. It's purpose is to call a <a class="el" href="a00064.html">Functor</a> instead of deleting the underlying pointee object. You have to set the callback functor by calling <a class="el" href="a00063.html#c55c8a149c74a27751204b0215c76041">SetCallBackFunction(const FunctorType &functor)</a>.<p>
Unfortunately, the functor argument is not a reference to the <a class="el" href="a00132.html">SmartPtr</a> but a void *. Making functor argument a reference to the pointer would require the <a class="el" href="a00063.html" title="Implementation of the StoragePolicy used by SmartPtr.">FunctionStorage</a> template to know the full definition of the <a class="el" href="a00132.html">SmartPtr</a>. <hr><h2>Member Function Documentation</h2>
