constexpr any () noexcept
Default constructor, creates an empty object.

template<typename _Tp , typename _VTp = _Decay_if_not_any<_Tp>, typename _Mgr = _Manager<_VTp>, enable_if_t*< *is_copy_constructible*< _VTp >::value &&!__is_in_place_type< _VTp >::value, bool > = true> *any (_Tp &&__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.

template<typename _Tp , typename… _Args, typename _VTp = decay_t<_Tp>, typename _Mgr = _Manager<_VTp>, __any_constructible_t< _VTp, _Args &&… > = false> any (in_place_type_t< _Tp >, _Args &&… __args)
Construct with an object created from __args as the contained object.

template<typename _Tp , typename _Up , typename… _Args, typename _VTp = decay_t<_Tp>, typename _Mgr = _Manager<_VTp>, __any_constructible_t< _VTp, initializer_list*< _Up >, _Args &&… > = false> *any (in_place_type_t< _Tp >, *initializer_list*< _Up > __il, _Args &&… __args)
Construct with an object created from __il and __args as the contained object.

~any ()
Destructor, calls reset()

template<typename _Tp , typename… _Args> __emplace_t< decay_t*< _Tp >, _Args… > *emplace (_Args &&… __args)
Emplace with an object created from __args as the contained object.

template<typename _Tp , typename _Up , typename… _Args> __emplace_t< decay_t*< _Tp >, *initializer_list*< _Up >, _Args &&… > *emplace (*initializer_list*< _Up > __il, _Args &&… __args)
Emplace with an object created from __il and __args as the contained object.

bool has_value () const noexcept
Reports whether there is a contained object or not.

template<typename _Tp > enable_if_t*< *is_copy_constructible*< _Decay_if_not_any< _Tp > >::value, *any & > operator= (_Tp &&__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 reset () noexcept
If not empty, destroy the contained 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.
