std::bad_any_cast(3) C++ Standard Libary std::bad_any_cast(3) NAME std::bad_any_cast - std::bad_any_cast Synopsis Defined in header <any> class bad_any_cast : public std::bad_cast; (since C++17) Defines a type of object to be thrown by the value-returning forms of std::any_cast on failure. Member functions constructor constructs a new bad_any_cast object (public member function) operator= replaces the bad_any_cast object (public member function) what returns the explanatory string (public member function) std::bad_any_cast::bad_any_cast bad_any_cast() noexcept; (1) (since C++17) bad_any_cast( const bad_any_cast& other ) noexcept; (2) (since C++17) Constructs a new bad_any_cast object with an implementation-defined null-terminated byte string which is accessible through what(). 1) Default constructor. 2) Copy constructor. If *this and other both have dynamic type std::bad_any_cast then std::strcmp(what(), other.what()) == 0. Parameters other - another exception object to copy std::bad_any_cast::operator= bad_any_cast& operator=( const bad_any_cast& other ) noexcept; (since C++17) Assigns the contents with those of other. If *this and other both have dynamic type std::bad_any_cast then std::strcmp(what(), other.what()) == 0 after as- signment. Parameters other - another exception object to assign with Return value *this std::bad_any_cast::what virtual const char* what() const noexcept; (since C++17) Returns the explanatory string. Parameters (none) Return value Pointer to a null-terminated string with explanatory information. The string is suitable for conversion and display as a std::wstring. The pointer is guaranteed to be valid at least until the exception object from which it is obtained is destroyed, or until a non-const member function (e.g. copy assignment operator) on the exception object is called. Notes Implementations are allowed but not required to override what(). Inherited from std::bad_cast Inherited from std::exception Member functions destructor destroys the exception object [virtual] (virtual public member function of std::exception) what returns an explanatory string [virtual] (virtual public member function of std::exception) http://cppreference.com 2024.06.10 std::bad_any_cast(3)
