<question><para>I see void pointers; is this [mess] type safe?</para></question>
|
||||
<answer>
|
||||
<para>Yes, <computeroutput>boost::function</computeroutput> is type
|
||||
safe even though it uses void pointers and pointers to functions
|
||||
returning void and taking no arguments. Essentially, all type
|
||||
information is encoded in the functions that manage and invoke
|
||||
function pointers and function objects. Only these functions are
|
||||
instantiated with the exact type that is pointed to by the void
|
||||
pointer or pointer to void function. The reason that both are required
|
||||
is that one may cast between void pointers and object pointers safely
|
||||
or between different types of function pointers (provided you don't
|
||||
invoke a function pointer with the wrong type). </para>

<question><para>Why are there workarounds for void returns? C++ allows them!</para></question>
|
||||
<answer><para>Void returns are permitted by the C++ standard, as in this code snippet:
|
||||
<programlisting>void f();
|
||||
void g() { return f(); }</programlisting>
|
||||
</para>
|
||||
|
||||
<para> This is a valid usage of <computeroutput>boost::function</computeroutput> because void returns are not used. With void returns, we would attempting to compile ill-formed code similar to:
|
||||
<programlisting>int f();
|
||||
void g() { return f(); }</programlisting>
|
||||
</para>
|
||||
|
||||
<para> In essence, not using void returns allows
|
||||
<computeroutput>boost::function</computeroutput> to swallow a return value. This is
|
||||
consistent with allowing the user to assign and invoke functions and
|
||||
function objects with parameters that don't exactly match.</para>

<question><para>Why (function) cloning?</para></question>
|
||||
<answer>
|
||||
<para>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.</para>

<title>Introduction</title>
|
||||
<para>The Boost.Function library contains a family of class templates
|
||||
that are function object wrappers. The notion is similar to a
|
||||
generalized callback. It shares features with function pointers in
|
||||
that both define a call interface (e.g., a function taking two integer
|
||||
arguments and returning a floating-point value) through which some
|
||||
implementation can be called, and the implementation that is invoked
|
||||
may change throughout the course of the program.</para>
|
||||
|
||||
<para> Generally, any place in which a function pointer would be used
|
||||
to defer a call or make a callback, Boost.Function can be used instead
|
||||
to allow the user greater flexibility in the implementation of the
|
||||
target. Targets can be any 'compatible' function object (or function
|
||||
pointer), meaning that the arguments to the interface designated by
|
||||
Boost.Function can be converted to the arguments of the target
|
||||
function object.</para>

Boost.Function has been partially redesigned to minimize the
|
||||
interface and make it cleaner. Several seldom- or never-used
|
||||
features of the older Boost.Function have been deprecated and will
|
||||
be removed in the near future. Here is a list of features that have
|
||||
been deprecated, the likely impact of the deprecations, and how to
|
||||
adjust your code:
|
||||
|
||||
<itemizedlist spacing="compact">
|
||||
<listitem><para>The <computeroutput>boost::function</computeroutput> class template syntax has
|
||||
changed. The old syntax, e.g., <computeroutput>boost::function<int, float,
|
||||
double, std::string></computeroutput>, has been changed to a more natural
|
||||
syntax <computeroutput>boost::function<int (float, double,
|
||||
std::string)></computeroutput>, where all return and argument types are
|
||||
encoded in a single function type parameter. Any other template
|
||||
parameters (e.g., the <computeroutput>Allocator</computeroutput>) follow this single
|
||||
parameter.</para>
|
||||
|
||||
<para> The resolution to this change depends on the
|
||||
abilities of your compiler: if your compiler supports template
|
||||
partial specialization and can parse function types (most do), modify
|
||||
your code to use the newer
|
||||
syntax (preferable) or directly use one of the
|
||||
<computeroutput>functionN</computeroutput> classes whose syntax has not
|
||||
changed. If your compiler does not support template partial
|
||||
specialization or function types, you must take the latter option and
|
||||
use the numbered Boost.Function classes. This option merely requires
|
||||
changing types such as <computeroutput>boost::function<void, int, int></computeroutput>
|
||||
to <computeroutput>boost::function2<void, int, int></computeroutput> (adding the number of
|
||||
function arguments to the end of the class name).</para>
|
||||
|
||||
<para> Support for the old syntax with the
|
||||
<computeroutput>boost::function</computeroutput> class template will persist for a short
|
||||
while, but will eventually be removed so that we can provide better
|
||||
error messages and link compatibility. </para></listitem>
|

<listitem><para>The invocation
|
||||
policy template parameter (<computeroutput>Policy</computeroutput>) has been deprecated
|

used feature.</para></listitem>
|

<listitem><para>The mixin template parameter

<title>Boost.Function vs. Function Pointers</title>

<para>Boost.Function has several advantages over function pointers, namely:

<listitem><para>Boost.Function allows arbitrary compatible function objects to be targets (instead of requiring an exact function signature).</para></listitem>

<title>Function object wrapper size</title>
|
||||
<para> 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.</para>

|
||||
<title>Copying efficiency</title>
|
||||
<para> 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 <computeroutput>ref</computeroutput>) if the cost of this cloning becomes prohibitive.</para>
|
||||
</section>
|
||||
|
||||
<section>
|
||||
<title>Invocation efficiency</title>
|
||||
<para> 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).</para>
|
||||

<section>
|
||||
<title>Combatting virtual function "bloat"</title>
|
||||
<para> The use of virtual functions tends to cause 'code bloat' on many compilers. When a class contains a virtual function, it is necessary to emit an additional function that classifies the type of the object. It has been our experience that these auxiliary functions increase the size of the executable significantly when many <computeroutput>boost::function</computeroutput> objects are used. </para>
|
||||
|
||||
<para> 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.</para>

<title>Acknowledgements</title>

|

<para> 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. Peter Dimov led us to the function
|
||||
declarator-based syntax.</para>

<para> Boost.Function has two syntactical forms: the preferred form
|
||||
and the portable form. The preferred form fits more closely with the
|
||||
C++ language and reduces the number of separate template parameters
|
||||
that need to be considered, often improving readability; however, the
|
||||
preferred form is not supported on all platforms due to compiler
|
||||
bugs. The compatible form will work on all compilers supported by
|
||||
Boost.Function. Consult the table below to determine which syntactic
|
||||
form to use for your compiler.

<title>Basic Usage</title> <para> A function wrapper is defined simply
|
||||
by instantiating the <computeroutput>function</computeroutput> class
|
||||
template with the desired return type and argument types, formulated
|
||||
as a C++ function type. Any number of arguments may be supplied, up to
|
||||
some implementation-defined limit (10 is the default maximum). The
|
||||
following declares a function object wrapper
|
||||
<computeroutput>f</computeroutput> that takes two
|
||||
<computeroutput>int</computeroutput> parameters and returns a
|
||||
<computeroutput>float</computeroutput>:

</para>
|

<para> By default, function object wrappers are empty, so we can create a

<para> Now we can use <computeroutput>f</computeroutput> to execute

the underlying function object

</para>
|

|

<para> We are free to assign any compatible function object to

<computeroutput>f</computeroutput>. If
|

<computeroutput>int_div</computeroutput> had been declared to take two
|

<computeroutput>long</computeroutput> operands, the implicit
|

conversions would have been applied to the arguments without any user
|
||||
interference. The only limit on the types of arguments is that they be
|
||||
CopyConstructible, so we can even use references and arrays:

<para> Invoking a function object wrapper that does not actually
|
||||
contain a function object is a precondition violation, much like
|
||||
trying to call through a null function pointer, and will throw a <classname>bad_function_call</classname> exception). We can check for an
|
||||
empty function object wrapper by using it in a boolean context (it evaluates <computeroutput>true</computeroutput> if the wrapper is not empty) or compare it against <computeroutput>0</computeroutput>. For instance:
|
||||
<programlisting name="function.tutorial.check_empty">if (f)
|
||||
std::cout << f(5, 3) << std::endl;
|
||||
else
|

std::cout << "f has no target, so it is unsafe to call" << std::endl;</programlisting>
|
||||
</para>
|
||||
|
||||
<para> Alternatively,
|
||||
<computeroutput><methodname>empty</methodname>()</computeroutput>
|
||||
method will return whether or not the wrapper is empty. </para>
|
||||
|
||||
<para> Finally, we can clear out a function target by assigning it to <computeroutput>0</computeroutput> or by calling the <computeroutput><methodname>clear</methodname>()</computeroutput> member function, e.g.,
|
||||
<programlisting name="function.tutorial.clear">f = 0;</programlisting>

<title>Free functions</title>
|

<para> 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:

<programlisting name="function.tutorial.mul_ints">float mul_ints(int x, int y) { return ((float)x) * y; }</programlisting>
|

<programlisting name="function.tutorial.use_mul_ints">f = &mul_ints;</programlisting>

<para> Note that the <computeroutput>&</computeroutput> isn't really necessary unless you happen to be using Microsoft Visual C++ version 6. </para>

<title>Member functions</title>
|

|

<para> 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:
|
||||
|
||||
<programlisting name="function.tutorial.X">struct X {
|

int foo(int);
|

<title>References to Functions</title> <para> 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 <computeroutput>ref</computeroutput>
|
||||
and <computeroutput>cref</computeroutput> functions to wrap a
|
||||
reference to a function object:
