Constructor & Destructor Documentation
std::experimental::any::any()[inline],[noexcept]
Default constructor, creates an empty object.
std::experimental::any::any(constany&__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)

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.
Member Function Documentation
voidstd::experimental::any::clear()[inline],[noexcept]
If not empty, destroy the contained object.
boolstd::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=(constany&__rhs)[inline]
Copy the state of another object.
voidstd::experimental::any::swap(any&__rhs)[inline],[noexcept]
Exchange state with another object.
consttype_info&std::experimental::any::type()const[inline],[noexcept]
The typeid of the contained object, or typeid(void) if empty.
