+
+[section Brief Description]
+
+The template __boost__factory__ lets you encapsulate a `new` expression
+as a function object, __boost__value_factory__ encapsulates a constructor
+invocation without `new`.
+
+ __boost__factory__<T*>()(arg1,arg2,arg3)
+ // same as new T(arg1,arg2,arg3)
+
+ __boost__value_factory__<T>()(arg1,arg2,arg3)
+ // same as T(arg1,arg2,arg3)
+
+For technical reasons the arguments to the function objects have to be
+LValues. A factory that also accepts RValues can be composed using the
+__boost__forward_adapter__ or __boost__bind__.
+
+[endsect]
+
+[section Background]
+
+In traditional Object Oriented Programming a Factory is an object implementing
+an interface of one or more methods that construct objects conforming to known
+interfaces.
+
+ // assuming a_concrete_class and another_concrete_class are derived
+ // from an_abstract_class
+
+ class a_factory
+ {
+ public:
+ virtual an_abstract_class* create() const = 0;
+ virtual ~a_factory() { }
+ };
+
+ class a_concrete_factory : public a_factory
+ {
+ public:
+ virtual an_abstract_class* create() const
+ {
+ return new a_concrete_class();
+ }
+ };
+
+ class another_concrete_factory : public a_factory
+ {
+ public:
+ virtual an_abstract_class* create() const
+ {
+ return new another_concrete_class();
+ }
+ };
+
+ // [...]
+
+ int main()
+ {
+ __boost__ptr_map__<__std__string__,a_factory> factories;
+
+ // [...]
+
+ factories.insert("a_name",std::auto_ptr<a_factory>(
+ new a_concrete_factory));
+ factories.insert("another_name",std::auto_ptr<a_factory>(
+ new another_concrete_factory));
+
+ // [...]
+
+ std::auto_ptr<an_abstract_class> x(factories.at(some_name).create());
+
+ // [...]
+ }
+
+This approach has several drawbacks. The most obvious one is that there is
+lots of boilerplate code. In other words there is too much code to express
+a rather simple intention. We could use templates to get rid of some of it
+but the approach remains inflexible:
+
+* We may want a factory that takes some arguments that are forwarded to
+ the constructor,
+* we will probably want to use smart pointers,
+* we may want several member functions to create different kinds of
+ objects,
+* we might not necessarily need a polymorphic base class for the objects,
+* as we will see, we do not need a factory base class at all,
+* we might want to just call the constructor - without `new` to create
+ an object on the stack, and
+* finally we might want to use customized memory management.
+
+Experience has shown that using function objects and generic Boost components
+for their composition, Design Patterns that describe callback mechanisms
+(typically requiring a high percentage of boilerplate code with pure Object
+Oriented methodology) become implementable with just few code lines and without
+extra classes.
+
+Factories are callback mechanisms for constructors, so we provide two class
+templates, __boost__value_factory__ and __boost__factory__, that encapsulate
+object construction via direct application of the constructor and the `new`
+operator, respectively.
+
+We let the function objects forward their arguments to the construction
+expressions they encapsulate. Over this __boost__factory__ optionally allows
+the use of smart pointers and __std_allocators__.
+
+Compile-time polymorphism can be used where appropriate,
+
+ template< class T >
+ void do_something()
+ {
+ // [...]
+ T x = T(a,b);
+
+ // for conceptually similar objects x we neither need virtual
+ // functions nor a common base class in this context.
+ // [...]
+ }
+
+Now, to allow inhomogeneous signatures for the constructors of the types passed
+in for `T` we can use __value_factory__ and __boost__bind__ to normalize between
+them.
+
+ template< class ValueFactory >
+ void do_something(ValueFactory make_obj = ValueFactory())
+ {
+ // [...]
+ typename ValueFactory::result_type x = make_obj(a,b);
+
+ // for conceptually similar objects x we neither need virtual
+ // functions nor a common base class in this context.
+ // [...]
+ }
+
+ int main()
+ {
+ // [...]
+
+ do_something(__boost__value_factory__<X>());
+ do_something(boost::bind(__boost__value_factory__<Y>(),_1,5,_2));
+ // construct X(a,b) and Y(a,5,b), respectively.
+
+ // [...]
+ }
+
+Maybe we want our objects to outlive the function's scope, in this case we
+have to use dynamic allocation;
+
+ template< class Factory >
+ whatever do_something(Factory new_obj = Factory())
+ {
+ typename Factory::result_type ptr = new_obj(a,b);
+
+ // again, no common base class or virtual functions needed,
+ // we could enforce a polymorphic base by writing e.g.
+ // boost::shared_ptr<base>
+ // instead of
+ // typename Factory::result_type
+ // above.
+ // Note that we are also free to have the type erasure happen
+ // somewhere else (e.g. in the constructor of this function's
+ // result type).
+
+ // [...]
+ }
+
+ // [... call do_something like above but with __factory__ instead
+ // of __value_factory__]
+
+Although we might have created polymorphic objects in the previous example,
+we have used compile time polymorphism for the factory. If we want to erase
+the type of the factory and thus allow polymorphism at run time, we can
+use __boost_function__ to do so. The first example can be rewritten as
+follows.
+
+ typedef boost::function< an_abstract_class*() > a_factory;
+
+ // [...]
+
+ int main()
+ {
+ __std__map__<__std__string__,a_factory> factories;
+
+ // [...]
+
+ factories["a_name"] = __boost__factory__<a_concrete_class*>();
+ factories["another_name"] =
+ __boost__factory__<another_concrete_class*>();
+
+ // [...]
+ }
+
+Of course we can just as easy create factories that take arguments and/or
+return __smart_pointers__.

+[heading Description]
+
+Function object template that dynamically constructs a pointee object for
+the type of pointer given as template argument. Smart pointers may be used
+for the template argument, given that `boost::pointee<Pointer>::type` yields
+the pointee type.
+
+If an __allocator__ is given, it is used for memory allocation and the
+placement form of the `new` operator is used to construct the object.
+A function object that calls the destructor and deallocates the memory
+with a copy of the Allocator is used for the second constructor argument
+of `Pointer` (thus it must be a __smart_pointer__ that provides a suitable
+constructor, such as __boost__shared_ptr__).
+
+If a third template argument is `factory_passes_alloc_to_smart_pointer`,
+the allocator itself is used for the third constructor argument of `Pointer`
+(__boost__shared_ptr__ then uses the allocator to manage the memory of its
+separately allocated reference counter).

+[section Changes]
+
+[heading Boost 1.58.0]
+
+In order to remove the dependency on Boost.Optional, the default parameter
+for allocators has been changed from `boost::none_t` to `void`.
+If you have code that has stopped working because it uses `boost::none_t`,
+a quick fix is to define `BOOST_FUNCTIONAL_FACTORY_SUPPORT_NONE_T`, which will
+restore support, but this will be removed in a future release.
+It should be be relatively easy to fix this properly.
+
+[endsect]
+
+[section Acknowledgements]
+
+Eric Niebler requested a function to invoke a type's constructor (with the
+arguments supplied as a Tuple) as a Fusion feature. These Factory utilities are
+a factored-out generalization of this idea.
+
+Dave Abrahams suggested Smart Pointer support for exception safety, providing
+useful hints for the implementation.
+
+Joel de Guzman's documentation style was copied from Fusion.
+
+Further, I want to thank Peter Dimov for sharing his insights on language
+details and their evolution.
