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

NAME
     std::experimental::shared_future - std::experimental::shared_future

Synopsis
	Defined in header <experimental/shared_future>
	template< class T > class shared_future;       (1) (concurrency TS)
	template< class T > class shared_future<T&>;   (2) (concurrency TS)
	template<>	    class shared_future<void>; (3) (concurrency TS)

	The	class	 template    std::experimental::shared_future	 extends
     std::shared_future with
	the following operations:

	  * an unwrapping constructor from future<shared_future<T>>;
	  * a member function is_ready to query whether  the  associated  shared
     state is
	    ready; and
	  * a member function then to attach a continuation to the future.

	There is no interoperation between std::experimental::shared_future and
	std::shared_future.

Member functions
	constructor   constructs a shared_future
		      (public member function)
	is_ready      checks if the shared state is ready
		      (public member function)
	then	      attaches a continuation to a shared_future
		      (public member function)
	operator=     assigns the contents
		      (public member function)

     Members identical to std::shared_future

Member functions
	destructor   destructs the future object
		     (public member function of std::shared_future<T>)

Getting the result
	get	     returns the result
		     (public member function of std::shared_future<T>)

State
	valid	     checks if the future has a shared state
		     (public member function of std::shared_future<T>)
	wait	     waits for the result to become available
		     (public member function of std::shared_future<T>)
		     waits  for  the  result, returns if it is not available for
     the specified
	wait_for     timeout duration
		     (public member function of std::shared_future<T>)
		     waits for the result, returns if it is not available  until
     specified
	wait_until   time point has been reached
		     (public member function of std::shared_future<T>)
