Check if UimaAsynchronousEngine is running

Hello!
    Is there any method to ask if the UimaAsynchronousEngine is still
running or is in the process of shutting down?

Thank you.
  Regards,
  Florin

One way to check is to see what processes are running.

Hello!
  Thank you for your helpful answers. I was using Jerry's approach : when
the client is stopping via the stop() method before this call of the method
I'm setting up a volatile boolean field that marks that the UIMAEngine is
stopping. Then, in a different part of my code where the engine is also
involved in the sending process, I'm checking up this
 boolean field.

Kind regards,
 Florin

Sorry, the state of the UimaAsynchronousEngine is currently not exposed. It
probably should be via isStopping() and/or isRunning() or something
similar, and even isStopped(). Presumably though, since your
application calls (?) stop() on the UimaAsynchronousEngine you know that at
least it is stopping. Also, adding support for registering user defined
callbacks on UimaAsynchronousEngine  lifecycle events be of interest as
well.
