std::experi...bad_any_cast(3)  C++ Standard Libary std::experi...bad_any_cast(3)

NAME
     std::experimental::bad_any_cast - std::experimental::bad_any_cast

Synopsis
	Defined in header <experimental/any>
	class bad_any_cast : public std::bad_cast;  (library fundamentals TS)

	Defines a type of object to be thrown by the value-returning forms of
	std::experimental::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::experimental::bad_any_cast::bad_any_cast

	bad_any_cast()	noexcept;			     (1) (library funda-
     mentals TS)
	bad_any_cast( const bad_any_cast& other ) noexcept; (2) (library  funda-
     mentals TS)

	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::experimental::bad_any_cast then  std::strcmp(what(),  other.what())
     == 0.

Parameters
	other - another exception object to copy

     std::experimental::bad_any_cast::operator=

	bad_any_cast& operator=( const bad_any_cast& other )	   (library fun-
     damentals TS)
	noexcept;

	Assigns  the  contents with those of other. If *this and other both have
     dynamic type
	std::experimental::bad_any_cast then  std::strcmp(what(),  other.what())
     == 0 after
	assignment.

Parameters
	other - another exception object to assign with

Return value
	*this

     std::experimental::bad_any_cast::what

	virtual const char* what() const noexcept;  (library fundamentals TS)

	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)
