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.

Definition at line 89 of file any.

Constructor & Destructor Documentation

std::experimental::any::any () [inline], [noexcept]

Default constructor, creates an empty object.

Definition at line 120 of file any.

std::experimental::any::any (const any & __other) [inline]

Copy constructor, copies the state of __other.

Definition at line 123 of file any.

std::experimental::any::any (any && __other) [inline], [noexcept]

Move constructor, transfer the state from __other.

Postcondition:

__other.empty() (not guaranteed for other implementations)

Definition at line 138 of file any.

template<typename _ValueType , typename _Tp = _Decay<_ValueType>, typename _Mgr = _Manager<_Tp>> std::experimental::any::any (_ValueType && __value) [inline]

Construct with a copy of __value as the contained object.

Definition at line 146 of file any.

std::experimental::any::~any () [inline]

Destructor, calls clear()

Definition at line 155 of file any.

Member Function Documentation

void std::experimental::any::clear () [inline], [noexcept]

If not empty, destroy the contained object.

Definition at line 188 of file any.

bool std::experimental::any::empty () const [inline], [noexcept]

Reports whether there is a contained object or not.

Definition at line 207 of file any.

any& std::experimental::any::operator= (const any & __rhs) [inline]

Copy the state of.

Definition at line 160 of file any.

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

Move assignment operator.

Postcondition:

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

Definition at line 171 of file any.

template<typename _ValueType > any& std::experimental::any::operator= (_ValueType && __rhs) [inline]

Store a copy of __rhs as the contained object.

Definition at line 179 of file any.

void std::experimental::any::swap (any & __rhs) [inline], [noexcept]

Exchange state with another object.

Definition at line 198 of file any.

const type_info& std::experimental::any::type () const [inline], [noexcept]

The typeid of the contained object, or typeid(void) if empty.

Definition at line 211 of file any.
