std::experimental::any(3)

💖 NAME 💖

std::experimental::any — a type-safe container of any type 🫶

(this is the libstdc++ page from the Library Functions Manual, bestie, so you're in exactly the right place ✨)

🎀 SYNOPSIS 🎀

#include <any>

👑 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 = false> 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 = true> 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. ✨
