NAME¶
std::experimental::any - A type-safe container of any type.
SYNOPSIS¶
Public Member Functions¶
any () noexcept
Default constructor, creates an empty object. template<typename _ValueType
, typename _Tp = _Decay<_ValueType>, typename _Mgr =
_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.
