template<typename T, typename IArch, typename OArch, typename Char, typename Copyable> T *hpx::any_cast(util::basic_any<IArch, OArch, Char, Copyable> *operand) noexcept#

Performs type-safe access to the contained object.

Parameters: operand – target any object
Returns: If operand is not a null pointer, and the typeid of the requested T matches that of the contents of operand, a pointer to the value contained by operand, otherwise a null pointer.

template<typename T, typename IArch, typename OArch, typename Char, typename Copyable> T const *hpx::any_cast(util::basic_any<IArch, OArch, Char, Copyable> const *operand) noexcept#

Performs type-safe access to the contained object.

Parameters: operand – target any object
Returns: If operand is not a null pointer, and the typeid of the requested T matches that of the contents of operand, a pointer to the value contained by operand, otherwise a null pointer.

template<typename T, typename IArch, typename OArch, typename Char, typename Copyable> T hpx::any_cast(util::basic_any<IArch, OArch, Char, Copyable> &operand)#

Performs type-safe access to the contained object. Let U be std::remove_cv_t<std::remove_reference_t<T>> The program is ill-formed if std::is_constructible_v<T, U&> is false.

Parameters: operand – target any object
Returns: static_cast<T>(*std::any_cast<U>(&operand))

template<typename T, typename IArch, typename OArch, typename Char, typename Copyable> T const &hpx::any_cast(util::basic_any<IArch, OArch, Char, Copyable> const &operand)#

Performs type-safe access to the contained object. Let U be std::remove_cv_t<std::remove_reference_t<T>> The program is ill-formed if std::is_constructible_v<T, const U&> is false.

Parameters: operand – target any object
Returns: static_cast<T>(*std::any_cast<U>(&operand))
