https://svn.boost.org/trac10/ticket/288 <pre class="wiki">Hello, May be I just can't find this, but... I would like to use the STL algorithms on STL containers of smart_ptrs. So I need an adapter that adapts a member function of a class that is pointed to by a smart_ptr. The standard boost::mem_fun does not do this. So, I wrote this class: template &lt;template&lt;class&gt; class PTR, typename S, typename T&gt; class mem_fun_ptr_t : public std::unary_function&lt;T*, S&gt; { public: explicit mem_fun_ptr_t(S (T::*p)()) : ptr(p) {} S operator()(PTR&lt;T&gt; p) const { return ((*p).*ptr)(); } private: S (T::*ptr)(); }; template &lt;template&lt;class&gt; class PTR, typename S, typename T&gt; inline mem_fun_ptr_t&lt;PTR,S,T&gt; mem_fun_ptr(S (T::*f)()) { return mem_fun_ptr_t&lt;PTR,S,T&gt;(f); } //============================ // // usage (e.g.): // ============= // class MyClass { // public: // void method() { /* Do something */ } // }; // //... // std::vector&lt;shared_ptr&lt;MyClass&gt; &gt; myVector; // //... (fill myVector) // // std::for_each(myVector.begin(),myVector.end(), // simon::mem_fun_ptr&lt;shared_ptr&gt;(&amp;MyClass::method)); // May be I am re-inventing the wheel? (If so please tell me :^) If not, could something like this be added to boost?
