<b>boost::mem_fn</b> is a generalization of the standard functions <b>std::mem_fun</b>
and <b>std::mem_fun_ref</b>. It supports member function pointers with more
than one argument, and the returned function object can take a pointer, a
reference, or a smart pointer to an object instance as its first argument. <STRONG>mem_fn</STRONG>
also supports pointers to data members by treating them as functions taking no
arguments and returning a (const) reference to the member.
</p>
<p>
The purpose of <b>mem_fn</b> is twofold. First, it allows users to invoke a
member function on a container with the familiar
</p>
<pre>
std::for_each(v.begin(), v.end(), boost::mem_fn(&amp;Shape::draw));
</pre>
<p>
syntax, even when the container stores smart pointers.
</p>
<p>
Second, it can be used as a building block by library developers that want
to treat a pointer to member function as a function object. A library might
define an enhanced <b>for_each</b> algorithm with an overload of the form:

<b>mem_fn</b> takes one argument, a pointer to a member function, and
returns a function object suitable for use with standard or user-defined
algorithms:

When documenting the feature, the library author will simply state:
</p>
<h4 style="MARGIN-LEFT: 20pt">template&lt;class It, class R, class T&gt; void
for_each(It first, It last, R (T::*pmf) ());</h4>

<p>
The returned function object takes the same arguments as the input member
function plus a "flexible" first argument that represents the object instance.
</p>
<p>
When the function object is invoked with a first argument <b>x</b> that is
neither a pointer nor a reference to the appropriate class (<b>X</b> in the
example above), it uses <tt>get_pointer(x)</tt> to obtain a pointer from
<b>x</b>. Library authors can "register" their smart pointer classes by
supplying an appropriate <b>get_pointer</b> overload, allowing <b>mem_fn</b>
to recognize and support them.
</p>
<p>
A <b>get_pointer</b> overload for <b>boost::shared_ptr</b> is supplied.

<p>
[Note: <b>get_pointer</b> is not restricted to return a pointer. Any object
that can be used in a member function call expression <tt>(x->*pmf)(...)</tt>
will work.]
</p>
<p>
[Note: the library uses an unqualified call to <b>get_pointer</b>. Therefore,
it will find, through argument-dependent lookup, <b>get_pointer</b> overloads
that are defined in the same namespace as the corresponding smart pointer
class, in addition to any <b>boost::get_pointer</b> overloads.]

All function objects returned by <b>mem_fn</b> expose a <b>result_type</b>

<h2><a name="FAQ">Frequently Asked Questions</a></h2>
<h3><a name="Q1">Can <b>mem_fn</b> be used instead of the standard
<b>std::mem_fun[_ref]</b> adaptors?</a></h3>
<p>
Yes. For simple uses, <b>mem_fn</b> provides additional functionality that
the standard adaptors do not. Complicated expressions that use <b>std::bind1st</b>,
<b>std::bind2nd</b> or <a href="../compose/index.htm"><b>Boost.Compose</b></a>
along with the standard adaptors can be rewritten using
<a href="bind.html"><b>boost::bind</b></a> that automatically takes advantage of
<b>mem_fn</b>.
</p>
<h3><a name="Q2">Should I replace every occurence of <b>std::mem_fun[_ref]</b>
with <b>mem_fn</b> in my existing code?</a></h3>
<p>
No, unless you have good reasons to do so. <b>mem_fn</b> is not 100% compatible
with the standard adaptors, although it comes pretty close. In particular,
<b>mem_fn</b> does not return objects of type
<b>std::[const_]mem_fun[1][_ref]_t</b>, as the standard adaptors do, and it is
not possible to fully describe the type of the first argument using the standard
<b>argument_type</b> and <b>first_argument_type</b> nested typedefs. Libraries
that need adaptable function objects in order to function might not like
<b>mem_fn</b>.
</p>
<h3><a name="Q3">Does <b>mem_fn</b> work with COM methods?</a></h3>
<p>
Yes, if you <a href="#stdcall">#define BOOST_MEM_FN_ENABLE_STDCALL</a>.
</p>
<h3><a name="Q4">Why isn't BOOST_MEM_FN_ENABLE_STDCALL defined automatically?</a></h3>
<p>
Non-portable extensions, in general, should default to off to prevent vendor
lock-in. Had BOOST_MEM_FN_ENABLE_STDCALL been defined automatically, you could
have accidentally taken advantage of it without realizing that your code is,
perhaps, no longer portable.

This implementation supports member functions with up to eight arguments.
This is not an inherent limitation of the design, but an implementation
detail.
</p>
<h3><a name="stdcall">&quot;__stdcall&quot; Support</a></h3>
<p>
Some platforms allow several types of member functions that differ by their

</p>
<p>
For example, Windows API functions and COM interface member functions use a

To use <b>mem_fn</b> with <b>__stdcall</b> member functions, <b>#define</b>
the macro <b>BOOST_MEM_FN_ENABLE_STDCALL</b> before including, directly or

</ul>
<h2>Purpose</h2>
<p>
The header <a href="../../boost/ref.hpp">boost/ref.hpp</a> defines the class template
<b>boost::reference_wrapper&lt;T&gt;</b>, the two functions <b>boost::ref</b> and
<b>boost::cref</b> that return instances of
<b>boost::reference_wrapper&lt;T&gt;</b>, and the two traits classes <b>boost::is_reference_wrapper&lt;T&gt;</b> and <b>boost::unwrap_reference&lt;T&gt;</b>.
</p>
<p>
The purpose of <b>boost::reference_wrapper&lt;T&gt;</b> is to contain a reference to
an object of type <b>T</b>. It is primarily used to "feed" references to
function templates (algorithms) that take their parameter by value.
</p>
<p>
To support this usage, <b>boost::reference_wrapper&lt;T&gt;</b> provides an implicit
conversion to <b>T &amp;</b>. This usually allows the function templates to
work on references unmodified.
</p>
<p>
<b>boost::reference_wrapper&lt;T&gt;</b> is both <b>CopyConstructible</b> and
<b>Assignable</b> (ordinary references are not <b>Assignable</b>).
</p>
<p>
The expression <b>boost::ref(x)</b> returns a <b>boost::reference_wrapper&lt;X&gt;(x)</b>
where <b>X</b> is the type of <b>x</b>. Similarly, <b>boost::cref(x)</b>
returns a <b>boost::reference_wrapper&lt;X const&gt;(x)</b>.
</p>
<p>The expression <b>boost::is_reference_wrapper&lt;T&gt;::value</b> is
<b>true</b> if <b>T</b> is a
<b>reference_wrapper</b>, and <b>false</b> otherwise.
<p>The type-expression <b>boost::unwrap_reference&lt;T&gt;::type</b>
is <b>T::type</b> if <b>T</b> is a
<b>reference_wrapper</b>, <b>T</b> otherwise.
