std::experimental::future(3)

NAME
std::experimental::future - std::experimental::future

Synopsis
   Defined in header <experimental/future>
   template< class T > class future; (1) (concurrency TS)
   template< class T > class future<T&>; (2) (concurrency TS)
   template<> class future<void>; (3) (concurrency TS)
   The class template std::experimental::future extends std::future with the following
   operations:
     * an unwrapping constructor from future<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.
   However, there is no interoperation between std::experimental::future and
   std::future.

Member functions
   constructor construct a future object
                 (public member function)
   is_ready checks if the shared state is ready
                 (public member function)
   then attaches a continuation to a future
                 (public member function)
   operator= moves the future object
                 (public member function) Members identical to std::future

Member functions
   Note that share() returns a std::experimental::shared_future<T>. The behavior is
   otherwise identical.
   destructor destructs the future object
                (public member function of std::future<T>)
   share transfers the shared state from *this to a shared_future and returns it
                (public member function of std::future<T>)

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

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