awaitCompletion

public boolean awaitCompletion(long timeout,
                               TimeUnit unit)
                        throws InterruptedException

Wait for completion: this method will wait until all submitted jobs have completed, subject to the provided timeout. This is inherently racy if external job submission is continuing; if the submitted jobs themselves submit new jobs, this will wait for those newly-submitted jobs to complete too.

Parameters:

timeout - The maximum time to wait.

unit - The unit used for the timeout.

Returns:

true if the submitted jobs have completed, false if they haven’t.

Throws:

InterruptedException

isCompleted

public boolean isCompleted()

Indicates whether all submitted jobs have completed.

Returns:

true if all submitted jobs have completed, false otherwise.
