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 92 of file experimental/any.

Constructor & Destructor Documentation

◆ any() [1/5]

std::experimental::fundamentals_v1::any::any ( )
inlinenoexcept

Default constructor, creates an empty object.

Definition at line 131 of file experimental/any.

◆ any() [2/5]

std::experimental::fundamentals_v1::any::any ( const any &  __other)
inline

Copy constructor, copies the state of __other.

Definition at line 134 of file experimental/any.

◆ any() [3/5]

std::experimental::fundamentals_v1::any::any ( any &&  __other)
inlinenoexcept

Move constructor, transfer the state from __other.

Postcondition
__other.empty() (this postcondition is a GNU extension)

Definition at line 151 of file experimental/any.

◆ any() [4/5]

template<typename _ValueType , typename _Tp = _Decay<_ValueType>, typename _Mgr = _Manager<_Tp>, typename enable_if< is_constructible< _Tp, _ValueType && >::value, bool >::type = true>
std::experimental::fundamentals_v1::any::any ( _ValueType &&  __value)
inline

Construct with a copy of __value as the contained object.

Definition at line 168 of file experimental/any.

◆ any() [5/5]

template<typename _ValueType , typename _Tp = _Decay<_ValueType>, typename _Mgr = _Manager<_Tp>, typename enable_if<!is_constructible< _Tp, _ValueType && >::value, bool >::type = false>
std::experimental::fundamentals_v1::any::any ( _ValueType &&  __value)
inline

Construct with a copy of __value as the contained object.

Definition at line 181 of file experimental/any.

◆ ~any()

std::experimental::fundamentals_v1::any::~any ( )
inline

Destructor, calls clear()

Definition at line 190 of file experimental/any.

Member Function Documentation

◆ __is_valid_cast()

template<typename _Tp >
static constexpr bool std::experimental::fundamentals_v1::any::__is_valid_cast ( )
inlinestaticconstexpr

Definition at line 289 of file experimental/any.

◆ clear()

void std::experimental::fundamentals_v1::any::clear ( )
inlinenoexcept

If not empty, destroy the contained object.

Definition at line 232 of file experimental/any.

◆ empty()

bool std::experimental::fundamentals_v1::any::empty ( ) const
inlinenoexcept

Reports whether there is a contained object or not.

Definition at line 274 of file experimental/any.

◆ operator=() [1/3]

template<typename _ValueType >
enable_if_t<!is_same< any, decay_t< _ValueType > >::value, any & > std::experimental::fundamentals_v1::any::operator= ( _ValueType &&  __rhs)
inline

Store a copy of __rhs as the contained object.

Definition at line 223 of file experimental/any.

◆ operator=() [2/3]

any & std::experimental::fundamentals_v1::any::operator= ( any &&  __rhs)
inlinenoexcept

Move assignment operator.

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

Definition at line 206 of file experimental/any.

◆ operator=() [3/3]

any & std::experimental::fundamentals_v1::any::operator= ( const any &  __rhs)
inline

Copy the state of another object.

Definition at line 195 of file experimental/any.

◆ swap()

void std::experimental::fundamentals_v1::any::swap ( any &  __rhs)
inlinenoexcept

Exchange state with another object.

Definition at line 242 of file experimental/any.

◆ type()

const type_info & std::experimental::fundamentals_v1::any::type ( ) const
inlinenoexcept

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

Definition at line 278 of file experimental/any.
