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:
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:
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.
