Examples of com.opengamma.engine.view.worker.ViewProcessWorker.terminate()

com.opengamma.engine.view.worker.ViewProcessWorker.terminate()
Terminate the executing job as soon as possible. The job must cease work on the view, cancel any jobs or requests that could cause work elsewhere, and allow any threads involved in the work to terminate or be returned to their respective pools.
This is an asynchronous termination request. To wait for the job to actually terminate follow this with a call to {@link #join}.

    assertFalse(executor.wasInterrupted());


    // Interrupting should cause everything to terminate gracefully
    ViewProcessImpl viewProcess = env.getViewProcess(vp, client.getUniqueId());
    ViewProcessWorker worker = env.getCurrentWorker(viewProcess);
    worker.terminate();
    worker.join(TIMEOUT);
    for (int i = 0; (i < TIMEOUT / 10) && !executor.wasInterrupted(); i++) {
      Thread.sleep(10);
    }
    assertTrue(executor.wasInterrupted());

    // Let go of the worker and allow it to die on its own. A computation cycle might be taking place, but it will
    // not update the view process with its result because it has been terminated. As far as the view process is
    // concerned, live computation has now stopped, and it may be started again immediately in a new thread.
    // There is no need to slow things down by attempting to join the job.
