std::experimental::any_cast(3)

NAME
std::experimental::any_cast - std::experimental::any_cast

Synopsis
   template<class ValueType> (1) (library fundamentals TS)
       ValueType any_cast(const any& operand);
   template<class ValueType> (2) (library fundamentals TS)
       ValueType any_cast(any& operand);
   template<class ValueType> (3) (library fundamentals TS)
       ValueType any_cast(any&& operand);
   template<class ValueType>
       const ValueType* any_cast(const any* operand) (4) (library fundamentals TS)
   noexcept;
   template<class ValueType> (5) (library fundamentals TS)
       ValueType* any_cast(any* operand) noexcept;
   Performs type-safe access to the contained object.
   For (1-3), the program is ill-formed if ValueType is not a reference and
   std::is_copy_constructible<ValueType>::value is false.

Parameters
   operand - target any object

Return value
   1) Returns
   *any_cast<std::add_const_t<std::remove_reference_t<ValueType>>>(&operand).
   2,3) Returns *any_cast<std::remove_reference_t<ValueType>>(&operand).
   4,5) If operand is not a null pointer, and the typeid of the requested ValueType
   matches that of the contents of operand, a pointer to the value contained by
   operand, otherwise a null pointer.

Exceptions
   1-3) Throws bad_any_cast if the typeid of the requested ValueType does not match
   that of the contents of operand.
