-
-    <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>
-    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>
-
-    <p>While <code>polymorphic_downcast</code> and <code>polymorphic_cast</code> work with built-in pointer types only,
-    <code>polymorphic_pointer_downcast</code> and <code>polymorphic_pointer_cast</code> are more generic versions
-    with support for any pointer type for which the following expressions would be valid:<br><br>

+[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, particularly to standard library IOStreams, 
+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).
+# The [@boost:boost/lexical_cast.hpp boost/lexical_cast.hpp] header 
+  provides [@boost:libs/lexical_cast/doc/html/index.html `lexical_cast<>`] general literal text conversions, such as an `int` represented as a `string`, or vice-versa. 
+
+[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);
+      ...
+    }
+```

+The C++ built-in `dynamic_cast` can be used for downcasts and
+crosscasts of pointers to polymorphic objects, but error notification in

-<p>The Conversion Library improves program safety and clarity by performing
-otherwise messy conversions.&nbsp; It includes cast-style function templates designed to complement the C++
-Standard's built-in casts.</p>
-<p>To reduce coupling, particularly to standard library IOStreams, the Boost
-Conversion Library is
-supplied by several headers:</p>
-<ul>
-  <li>The <a href="cast.htm">boost/polymorphic_cast.hpp and boost/polymorphic_pointer_cast.hpp</a> 
-    headers provide <b>polymorphic_cast&lt;&gt;</b>,
-    <b>polymorphic_downcast&lt;&gt;</b> and <b>polymorphic_pointer_downcast&lt;&gt;</b> to perform safe casting between
-  polymorphic types.<br>
-  </li>
-  <li>The boost/implicit_cast.hpp header provides <b>implicit_cast&lt;&gt;</b>
-    to perform implicit casts only (no down-cast, no void*->T*, no U->T if T has only explicit constructors for U).<br>
-  </li>
-  <li>The <a href="../../doc/html/boost_lexical_cast.html">boost/lexical_cast</a> header provides <b>lexical_cast&lt;&gt;</b>
-    general literal text conversions, such as an <code>int</code> represented as
-    a <code>string</code>, or vice-versa.</li>

Edward Diener	df86cb59c4	[skip ci] Add "cxxstd" json field. The "cxxstd" json field is being added to each Boost library's meta json information for libraries in order to specify the minumum C++ standard compilation level. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out.	2021-01-19 12:48:45 -05:00

Julien DELACROIX	e130cd860c	boost::polymorphic_downcast only supports raw pointer cast, which is a gap compared to static_cast. To make it clear: Base* base = new Base(); static_cast<Derived>(base) ===> OK static_cast<Derived&>(base) ===> OK boost::polymorphic_downcast<Derived>(base) ===> OK boost::polymorphic_downcast<Derived&>(base) ===> IMPOSSIBLE boost::polymorphic_downcast being a kind of "debug-safe version" of static_cast, it should provide the same capabilities. This patch extend boost::polymorphic_downcast to support references just like static_cast does. This is achieved by introducing a partial specialization for references. Unit tests have been updated accordingly.	2019-12-09 08:51:10 +01:00
