<h2><a name="Cast Functions">Cast Functions</a></h2>
<p>The header <a href="../../boost/cast.hpp">boost/cast.hpp</a> provides <code>
<a href="#Polymorphic_cast">polymorphic_cast</a> and</code> <a href=
"#Polymorphic_cast"><code>polymorphic_downcast</code></a> function templates designed to
complement the C++ built-in casts.</p>
<p>The program <a href="cast_test.cpp">cast_test.cpp</a> can be used to
verify these function templates work as expected.</p>
<h3><a name="Polymorphic_cast">Polymorphic casts</a></h3>
<p>Pointers to polymorphic objects (objects of classes which define at
least one virtual function) are sometimes downcast or crosscast.
Downcasting means casting from a base class to a derived class.
Crosscasting means casting across an inheritance hierarchy diagram, such
as from one base to the other in a <code>Y</code> diagram hierarchy.</p>
<p>Such casts can be done with old-style casts, but this approach is
never to be recommended. Old-style casts are sorely lacking in type
safety, suffer poor readability, and are difficult to locate with search
tools.</p>
<p>The C++ built-in <code>static_cast</code> can be used for efficiently
downcasting pointers to polymorphic objects, but provides no error
detection for the case where the pointer being cast actually points to
the wrong derived class. The <code>polymorphic_downcast</code> template retains
the efficiency of <code>static_cast</code> for non-debug compilations, but for
debug compilations adds safety via an assert() that a <code>dynamic_cast</code>
succeeds.</p>
<p>The C++ built-in <code>dynamic_cast</code> can be used for downcasts and
crosscasts of pointers to polymorphic objects, but error notification in
the form of a returned value of 0 is inconvenient to test, or worse yet,
easy to forget to test. The throwing form of <code>dynamic_cast</code>, which
works on references, can be used on pointers through the ugly expression
&amp;<code>dynamic_cast&lt;T&amp;&gt;(*p)</code>, which causes undefined
behavior if <code>p</code> is <code>0</code>. The <code>polymorphic_cast</code>
template performs a <code>dynamic_cast</code> on a pointer, and throws an
exception if the <code>dynamic_cast</code> returns 0.</p>
<p>A <code>polymorphic_downcast</code> should be used for
downcasts that you are certain should succeed. Error checking is
only performed in translation units where <code>NDEBUG</code> is
not defined, via
<pre> assert( dynamic_cast&lt;Derived&gt;(x) == x )
</pre> where <code>x</code> is the source pointer. This approach
ensures that not only is a non-zero pointer returned, but also
that it is correct in the presence of multiple inheritance.
Attempts to crosscast using <code>polymorphic_downcast</code> will
fail to compile.
<b>Warning:</b> Because <code>polymorphic_downcast</code> uses assert(), it
violates the One Definition Rule (ODR) if NDEBUG is inconsistently
defined across translation units. [See ISO Std 3.2]
</p><p>
For crosscasts, or when the success of a cast can only be known at
runtime, or when efficiency is not important,
<code>polymorphic_cast</code> is preferred. </p>
<p>The C++ built-in <code>dynamic_cast</code> must be used to cast references
rather than pointers. It is also the only cast that can be used to check
whether a given interface is supported; in that case a return of 0 isn't
an error condition.</p>

[section Description]
The Conversion Library improves program safety and clarity by performing
otherwise messy conversions. It includes cast-style function templates designed
to complement the C++ Standard's built-in casts.
To reduce coupling, the Boost Conversion Library is supplied by several headers:
# The [@boost:boost/polymorphic_cast.hpp boost/polymorphic_cast.hpp] header
provides [link polymorphic_cast `polymorphic_cast<>`] and
[link polymorphic_downcast `polymorphic_downcast<>`]
to perform safe casting between polymorphic types.
# The [@boost:boost/polymorphic_pointer_cast.hpp boost/polymorphic_pointer_cast.hpp] header
provides [link polymorphic_pointer_cast `polymorphic_pointer_cast<>`] and
[link polymorphic_pointer_cast `polymorphic_pointer_downcast<>`]
# The [@boost:boost/implicit_cast.hpp boost/implicit_cast.hpp] header provides `implicit_cast<>`
to perform implicit casts only (no down-cast, no void*->T*, no U->T if T has only explicit constructors for U).
[endsect]
[section Polymorphic casts]
Pointers to polymorphic objects (objects of classes which define at
least one virtual function) are sometimes downcast or crosscast.
Downcasting means casting from a base class to a derived class.
Crosscasting means casting across an inheritance hierarchy diagram, such
as from one base to the other in a [^Y] diagram hierarchy.
Such casts can be done with old-style casts, but this approach is
never to be recommended. Old-style casts are sorely lacking in type
safety, suffer poor readability, and are difficult to locate with search
tools.
[#polymorphic_downcast]
[section polymorphic_downcast]
The C++ built-in `static_cast` can be used for efficiently
downcasting pointers to polymorphic objects, but provides no error
detection for the case where the pointer being cast actually points to
the wrong derived class. The `polymorphic_downcast` template retains
the efficiency of `static_cast` for non-debug compilations, but for
debug compilations adds safety via an `assert()` that a `dynamic_cast`
succeeds.
A `polymorphic_downcast` should be used for
downcasts that you are certain should succeed. Error checking is
only performed in translation units where `NDEBUG` is
not defined, via
```
assert( dynamic_cast<Derived>(x) == x )
```
where `x` is the source pointer. This approach
ensures that not only is a non-zero pointer returned, but also
that it is correct in the presence of multiple inheritance.
Attempts to crosscast using `polymorphic_downcast` will
fail to compile.
[warning Because `polymorphic_downcast` uses `assert()`, it
violates the One Definition Rule (ODR) if `NDEBUG` is inconsistently
defined across translation units. See ISO Std 3.2]
[h4 Example:]
```
#include <boost/polymorphic_cast.hpp>
...
class Fruit { public: virtual ~Fruit(){}; ... };
class Banana : public Fruit { ... };
...
void f( Fruit * fruit ) {
// ... logic which leads us to believe it is a Banana
Banana * banana = boost::polymorphic_downcast<Banana*>(fruit);
...
}
```
[endsect]
[#polymorphic_cast]
[section polymorphic_cast]
The C++ built-in `dynamic_cast` can be used for downcasts and
crosscasts of pointers to polymorphic objects, but error notification in
the form of a returned value of 0 is inconvenient to test, or worse yet,
easy to forget to test. The throwing form of `dynamic_cast`, which
works on references, can be used on pointers through the ugly expression
`&dynamic_cast<T&>(*p)`, which causes undefined
behavior if `p` is `0`. The `polymorphic_cast`
template performs a `dynamic_cast` on a pointer, and throws an
exception if the `dynamic_cast` returns 0.
For crosscasts, or when the success of a cast can only be known at runtime,
or when efficiency is not important, `polymorphic_cast` is preferred.
The C++ built-in `dynamic_cast` must be used to cast references rather than pointers.
It is also the only cast that can be used to check whether a given interface is supported; in that case a return of 0 isn't an error condition.

[#polymorphic_pointer_cast]
[section polymorphic_pointer_cast]
While `polymorphic_downcast` and `polymorphic_cast` work with built-in pointer types only,
`polymorphic_pointer_downcast` and `polymorphic_pointer_cast` are more generic versions
with support for any pointer type for which the following expressions would be valid:
For `polymorphic_pointer_downcast`:
```
static_pointer_cast<Derived>(p);
dynamic_pointer_cast<Derived>(p);
```
For `polymorphic_pointer_cast`:
```
dynamic_pointer_cast<Derived>(p);
!p; // conversion to bool with negation
```
This includes C++ built-in pointers, `std::shared_ptr`,
`boost::shared_ptr`, `boost::intrusive_ptr`, etc.
[h4 Example:]
```
#include <boost/polymorphic_pointer_cast.hpp>
class Fruit { public: virtual ~Fruit(){} };
class Banana : public Fruit {};
// Use one of these:
using FruitPtr = Fruit*;
using FruitPtr = std::shared_ptr<Fruit>;
using FruitPtr = boost::shared_ptr<Fruit>;
using FruitPtr = boost::intrusive_ptr<Fruit>;
void f(FruitPtr fruit) {
// ... logic which leads us to believe it is a banana
auto banana = boost::polymorphic_pointer_downcast<Banana>(fruit);
...
}
```

[section History]
`polymorphic_cast` was suggested by Bjarne Stroustrup in "The C++ Programming Language".
`polymorphic_downcast` was contributed by [@http://www.boost.org/people/dave_abrahams.htm Dave Abrahams].
`polymorphic_pointer_downcast` was contributed by [@http://www.boost.org/people/boris_rasin.htm Boris Rasin]
and `polymorphic_pointer_cast` by Antony Polukhin.
`polymorphic_downcast` overload for references was contributed by Julien Delacroix.
An old `numeric_cast` that was contributed by [@http://www.boost.org/people/kevlin_henney.htm Kevlin Henney]
is now superseded by the [@boost:numeric_conversion/doc/html/html/boost_numericconversion/improved_numeric_cast__.html Boost Numeric Conversion Library]
