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>)
