A Future represents the result of an asynchronous computation.
Definition Future.h:88
virtual V get()=0
Waits if necessary for the computation to complete, and then retrieves its result.

Definition Future.h:91
virtual V get(long long timeout, const TimeUnit &unit)=0
Waits if necessary for at most the given time for the computation to complete, and then retrieves its...
virtual bool cancel(bool mayInterruptIfRunning)=0
Attempts to cancel execution of this task.
virtual ~FutureType()
Definition Future.h:32
virtual bool isCancelled() const =0
Returns true if this task was canceled before it completed normally.
virtual bool isDone() const =0
Returns true if this task completed.
A TimeUnit represents time durations at a given unit of granularity and provides utility methods to c...
