NAME

       std::experimental::any - A type-safe container of any type.

SYNOPSIS

       #include <any>

   Public Member Functions
       any () noexcept
           Default constructor, creates an empty object.

           _Manager<_Tp>, typename enable_if< is_constructible< _Tp, _ValueType && >::value, bool
           >::type  = true> any (_ValueType &&__value)
           Construct with a copy of __value as the contained object.
       template<typename _ValueType , typename _Tp  = _Decay<_ValueType>, typename _Mgr  =
           _Manager<_Tp>, typename enable_if<!is_constructible< _Tp, _ValueType && >::value, bool
           >::type  = false> any (_ValueType &&__value)
           Construct with a copy of __value as the contained object.
       any (any &&__other) noexcept
           Move constructor, transfer the state from __other.
       any (const any &__other)
           Copy constructor, copies the state of __other.
       ~any ()
           Destructor, calls clear()
       void clear () noexcept
           If not empty, destroy the contained object.
       bool empty () const noexcept
           Reports whether there is a contained object or not.
       template<typename _ValueType > enable_if_t<!is_same< any, decay_t< _ValueType > >::value,
           any & > operator= (_ValueType &&__rhs)
           Store a copy of __rhs as the contained object.
       any & operator= (any &&__rhs) noexcept
           Move assignment operator.
       any & operator= (const any &__rhs)
           Copy the state of another object.
       void swap (any &__rhs) noexcept
           Exchange state with another object.
       const type_info & type () const noexcept
           The typeid of the contained object, or typeid(void) if empty.

Detailed Description

       A type-safe container of any type.

       An any object's state is either empty or it stores a contained object of CopyConstructible
       type.

Constructor & Destructor Documentation

   std::experimental::any::any () [inline],  [noexcept]
       Default constructor, creates an empty object.

   std::experimental::any::any (const any & __other) [inline]
       Copy constructor, copies the state of __other.

   std::experimental::any::any (any && __other) [inline],  [noexcept]
       Move constructor, transfer the state from __other.

       Postcondition
           __other.empty() (this postcondition is a GNU extension)

   template<typename _ValueType , typename _Tp  = _Decay<_ValueType>, typename _Mgr  =
       _Manager<_Tp>, typename enable_if< is_constructible< _Tp, _ValueType && >::value, bool
       >::type  = true> std::experimental::any::any (_ValueType && __value) [inline]
       Construct with a copy of __value as the contained object.

   template<typename _ValueType , typename _Tp  = _Decay<_ValueType>, typename _Mgr  =
       _Manager<_Tp>, typename enable_if<!is_constructible< _Tp, _ValueType && >::value, bool
       >::type  = false> std::experimental::any::any (_ValueType && __value) [inline]
       Construct with a copy of __value as the contained object.

   std::experimental::any::~any () [inline]
       Destructor, calls clear()

Member Function Documentation

   void std::experimental::any::clear () [inline],  [noexcept]
       If not empty, destroy the contained object.

   bool std::experimental::any::empty () const [inline],  [noexcept]
       Reports whether there is a contained object or not.

   template<typename _ValueType > enable_if_t<!is_same< any, decay_t< _ValueType > >::value, any
       & > std::experimental::any::operator= (_ValueType && __rhs) [inline]
       Store a copy of __rhs as the contained object.

   any & std::experimental::any::operator= (any && __rhs) [inline],  [noexcept]
       Move assignment operator.

       Postcondition
           __rhs.empty() (not guaranteed for other implementations)

   any & std::experimental::any::operator= (const any & __rhs) [inline]
       Copy the state of another object.

   void std::experimental::any::swap (any & __rhs) [inline],  [noexcept]
       Exchange state with another object.

   const type_info & std::experimental::any::type () const [inline],  [noexcept]
       The typeid of the contained object, or typeid(void) if empty.
