## Detailed Description

A type-safe container for single values of value types, as described in n3804 "Any Library Proposal (Revision 3)".

## any_cast() [1/5]

template<typename _ValueType >

_ValueType std::experimental::fundamentals_v1::any_cast | ( | const any & | __any | ) |

inline

Access the contained object.

Template Parameters

  _ValueType | A const-reference or CopyConstructible type.

Parameters

  __any | The object to access.

Returns
  The contained object.

Exceptions

  bad_any_cast | If `__any.type() != typeid(remove_reference_t<_ValueType>)`

## any_cast() [4/5]

template<typename _ValueType >

const _ValueType* std::experimental::fundamentals_v1::any_cast | ( | const any * | __any | ) |

inline noexcept

Access the contained object.

Template Parameters

  _ValueType | The type of the contained object.

Parameters

  __any | A pointer to the object to access.

Returns
  The address of the contained object if `__any != nullptr && __any.type() == typeid(_ValueType)` , otherwise a null pointer.
