如何等待PooledThreadExecutor完成？

Question

Regarding the AWS c++ sdk thread pool feature, is there an elegant way to wait for PooledThreadExecutor to finish all tasks in the queue after calling -for example- getObjectAsync many times ?

Or should I just use getObjectCallable, store references to all future objects in an array, loop the array and wait for each one.

Answer 1

The destructor of the PooledThreadExecutor will join its threads. Effectively as if you would have used the Callable version and waited till the request returned before exiting.
