std::experimental::any(3)      C++ Standard Libary     std::experimental::any(3)

NAME
     std::experimental::any - std::experimental::any

Synopsis
	Defined in header <experimental/any>
	class any;			      (library fundamentals TS)

	The  class  any describes a type-safe container for single values of any
     type.

	1) An object of class any stores an instance of any type that  satisfies
     the
	constructor  requirements  or  is  empty, and this is referred to as the
     state of the
	class any object. The stored instance is called  the  contained  object.
     Two states are
	equivalent if they are either both empty or if both are not empty and if
     the
	contained objects are equivalent.
	2)  The  non-member  any_cast  functions provide type-safe access to the
     contained
	object.

	Implementations are encouraged to avoid dynamic  allocations  for  small
     objects, but
	such an optimization may only be applied to types that for which
	std::is_nothrow_move_constructible returns true.

Member functions
	constructor   constructs an any object
		      (public member function)
	operator=     assigns an any object
		      (public member function)
	destructor    destroys an any object
		      (public member function)

Modifiers
	clear	      destroys contained object
		      (public member function)
	swap	      swaps two any objects
		      (public member function)

Observers
	empty	      checks if object holds a value
		      (public member function)
	type	      returns the typeid of the contained value
		      (public member function)

Non-member functions
	swap	 swaps two any instances
		 (function)
	any_cast type-safe access to the contained object
		 (function template)

Helper classes
	bad_any_cast		   exception thrown by the value-returning forms
     of any_cast
	(library fundamentals TS) on a type mismatch
				  (class)
