The class template
std::experimental::future
extends
std::future
with the following operations:
-
an
unwrapping constructor
from
future<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.
However, there is no interoperation between
std::experimental::future
and
std::future
.
Member functions
construct a
future
object
(public member function) |
|
|
checks if the shared state is ready
(public member function) |
|
|
attaches a continuation to a future
(public member function) |
|
|
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.
|
destructs the future object
(public member function of
std::future<T>
)
|
|
|
transfers the shared state from
*
this
to a
shared_future
and returns it
(public member function of
std::future<T>
)
|
|
Getting the result |
|
|
returns the result
(public member function of
std::future<T>
)
|
|
State |
|
|
checks if the future has a shared state
(public member function of
std::future<T>
)
|
|
|
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 timeout duration
(public member function of
std::future<T>
)
|
|
|
waits for the result, returns if it is not available until specified time point has been reached
(public member function of
std::future<T>
)
