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)

   template<typename_ValueType,typename_Tp=_Decay<_ValueType>,typename_Mgr=_Manager<_Tp>,typenameenable_if<is_constructible<_Tp,_ValueType&&>::value,bool>::type=true>std::experimental::any::any(_ValueType&&__value)[inline]
       Construct with a copy of __value as the contained object.

   template<typename_ValueType,typename_Tp=_Decay<_ValueType>,typename_Mgr=_Manager<_Tp>,typenameenable_if<!is_constructible<_Tp,_ValueType&&>::value,bool>::type=false>std::experimental::any::any(_ValueType&&__value)[inline]
       Construct with a copy of __value as the contained object.

   std::experimental::any::~any()[inline]
       Destructor, calls clear()

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.
