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. _GLIBCXX_NODISCARD 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
