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_readyto query whether the associated shared state is ready; and - a member function
thento 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 (public member function) |
|
| checks if the shared state is ready (public member function) |
|
attaches a continuation to a shared_future (public member function) |
|
| assigns the contents (public member function) |
Member functions
| destructs the future object (public member function of std::shared_future<T>)
|
|
Getting the result | |
| returns the result (public member function of std::shared_future<T>) |
|
State | |
| checks if the future has a shared state (public member function of std::shared_future<T>) |
|
| 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 timeout duration (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 (public member function of std::shared_future<T>) |
