std::experimental::shared_future: std::experimental::shared_future

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


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


Members identical to std::shared_future

Member functions


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

Getting the result


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

State


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