(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.

Members identical to std::future

Member functions

Note that share() returns a std::experimental::shared_future<T>. The behavior is otherwise identical.

destructs the future object
(public member function of std::future<T>) [edit]
transfers the shared state from *this to a shared_future and returns it
(public member function of std::future<T>) [edit]
Getting the result
returns the result
(public member function of std::future<T>) [edit]
checks if the future has a shared state
(public member function of std::future<T>) [edit]
waits for the result to become available
(public member function of std::future<T>) [edit]
waits for the result, returns if it is not available for the specified timeout duration
(public member function of std::future<T>) [edit]
waits for the result, returns if it is not available until specified time point has been reached
(public member function of std::future<T>) [edit]
