<h2>Q: Why (function) cloning? </h2>
|
||||
<p> In November and December of 2000, the issue of cloning vs. reference counting was debated at length and it was decided that cloning gave more predictable semantics. I won't rehash the discussion here, but if it cloning is incorrect for a particular application a reference-counting allocator could be used.
|
||||
|
||||
<h2>Q: How do I assign from a member function?</h2>
|
||||
<p> Member function assignments are not included directly in <code>boost::function</code> because they do not conform to the syntax of function objects. Several libraries exist to wrap member functions in a function object and/or bind the first argument to the member function (the <code>this</code> pointer). A few libraries are <a href="tutorial.html#member_func">described</a> in the <a href="../index.html">Boost.Function</a> documentation.

This requires that a pointer to member function of the form <code>R (X::*mf)(Arg1, Arg2, ..., Arg<em>N</em>) <em>cv-quals</em></code> be adapted to a function object with the following function call operator overloads:

<pre>

<p> Free function pointers can be considered singleton function objects with const function call operators, and can therefore be directly used with the function object wrappers:
|
||||
<pre>
|
||||
float mul_ints(int x, int y) { return ((float)x) * y; }
|
||||
f = &mul_ints;
|
||||
f = &mul_ints;
|
||||

<h3>Member functions</h3>
|
||||
<a name="member_func">
|
||||
<p> In many systems, callbacks often call to member functions of a particular
|
||||
object. This is often referred to as "argument binding", and is beyond the scope of Boost.Function. The use of member functions directly, however, is supported, so the following code is valid:
|
||||
<pre>
|
||||
struct X {
|
||||
int foo(int);
|
||||
};
|
||||
|
||||
boost::function<int, X*, int> f;
|
||||
f = &X::foo;
|
||||
|
||||
X x;
|
||||
f(&x, 5);
|
||||
</pre>
|
||||
<p> Several libraries exist that support argument binding. Three such libraries are summarized below:

object. Handling argument binding is beyond the scope of Boost.Function. However, there are several libraries that perform 'argument binding', including
|
||||
<ul>
|
||||
<li> <a href="../../bind/bind.html">Boost.Bind</a>. This library allows binding of arguments for any function object. It is lightweight and very portable.</li>
|
||||
|
||||
<li> The C++ Standard library. Using <code>std::bind1st</code> and <code>std::mem_fun</code> together one can bind the object of a pointer-to-member function for use with Boost.Function:
|
||||
<pre>
|
||||
struct X {
|
||||
@ -97,34 +81,12 @@ object. This is often referred to as "argument binding", and is beyond the scope
|
||||
f(5); // Call x.foo(5)</pre></li>
|
||||
|
||||
<li><a href="http://lambda.cs.utu.fi/">The Lambda library</a>. This library provides a powerful composition mechanism to construct function objects that uses very natural C++ syntax. Lambda requires a compiler that is reasonably conformant to the C++ standard. Note that it is not a Boost library.</li>
|
||||
|
||||
<li>Peter Dimov's <a href="http://groups.yahoo.com/group/boost/files/bind/bind.hpp">bind</a> library. It has a smaller scope than the Lambda Library but is more tolerant of broken compilers. It is an unreviewed library in development.</li>
|
||||
</ul>
|
||||
|
||||
<h3>References to Functions</h3>
|
||||
<p> In some cases it is expensive (or semantically incorrect) to have
|
||||
Boost.Function clone a function object. In such cases, it is possible
|
||||
to request that Boost.Function keep only a reference to the actual
|
||||
function object. This is done using the <a
|
||||
href="../../bind/ref.html"><code>ref</code></a> and <a
|
||||
href="../../bind/ref.html"><code>cref</code></a> functions to wrap a
|
||||
reference to a function object:
|
||||
|
||||
<pre>
|
||||
stateful_type a_function_object;
|
||||
boost::function<int, int> f;
|
||||
f = ref(a_function_object);
|
||||
|
||||
boost::function<int, int> f2(f);
|
||||
</pre>
|
||||
|
||||
Here, <code>f</code> will not make a copy of
|
||||
<code>a_function_object</code>, nor will <code>f2</code> when it is
|
||||
targeted to <code>f</code>'s reference to
|
||||
<code>a_function_object</code>. Additionally, when using references to
|
||||
function objects, Boost.Function will not throw exceptions during
|
||||
assignment or construction.
|
||||
|
||||
<h2><a name="family">The <code>function</code> family</a></h2>
|
||||
<p> The header <<a href="../../../boost/function.hpp">boost/function.hpp</a>> defines the primary entry point to the function object wrappers, the class template <code>boost::function</code>. This class template is essentially a thin wrapper around a set of similar numbered function object wrappers, <code>boost::function0</code>, <code>boost::function1</code>, etc., where the number indicates the number of arguments passed to the function object target. The declaration of <code>f</code> above could also be written as:

|
||||
<p> Function object wrappers will be the size of two function pointers plus one function pointer or data pointer (whichever is larger). On common 32-bit platforms, this amounts to 12 bytes per wrapper. Additionally, the function object target will be allocated on the heap.
|
||||
|
||||
<h3>Copying efficiency</h3>
|
||||
<p> Copying function object wrappers may require allocating memory for a copy of the function object target. The default allocator may be replaced with a faster custom allocator or one may choose to allow the function object wrappers to only store function object targets by reference (using <a href="../bind/ref.html"><code>ref</code></a>) if the cost of this cloning becomes prohibitive.

|
||||
|
||||
<h3>Invocation efficiency</h3>
|
||||
<p> With a properly inlining compiler, an invocation of a function object requires one call through a function pointer. If the call is to a free function pointer, an additional call must be made to that function pointer (unless the compiler has very powerful interprocedural analysis).
|
||||

|
||||
|
||||
<p> In Boost.Function, an alternative but equivalent approach was taken using free functions instead of virtual functions. The Boost.Function object essentially holds two pointers to make a valid target call: a void pointer to the function object it contains and a void pointer to an "invoker" that can call the function object, given the function pointer. This invoker function performs the argument and return value conversions Boost.Function provides. A third pointer points to a free function called the "manager", which handles the cloning and destruction of function objects. The scheme is typesafe because the only functions that actually handle the function object, the invoker and the manager, are instantiated given the type of the function object, so they can safely cast the incoming void pointer (the function object pointer) to the appropriate type.
|
||||
|
||||
<p> A compiler with strong interprocedural analysis could significantly reduce the overhead associated with virtual function calls such that the alternative used by Boost.Function is less efficient. No compiler has yet been found where this is true, but when it does occur the BOOST_FUNCTION_USE_VIRTUAL_FUNCTIONS macro can be defined to revert to the simpler implementation based on virtual functions.

<p> Many people were involved in the construction of this library. William Kempf, Jesse Jones and Karl Nelson were all extremely helpful in isolating an interface and scope for the library. John Maddock managed the formal review, and many reviewers gave excellent comments on interface, implementation, and documentation.
