Yes, it is safe to call isPending() on a task from another thread.

Regarding org.apache.pivot.util.concurrent.Task<V> derived tasks:

 

Is it safe for one task running on a background thread to call the
isPending() method of some other task that is running on a different
background thread?

 

Our particular use case involves two background tasks that need to
coordinate (minimally) with each other.  A second task wants to keep
running at least as long as the first task is still in progress.  So the
second task periodically checks theisPending() method of the first task.
