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.
