Class java.util.concurrent.ScheduledThreadPoolExecutor

Examples of java.util.concurrent.ScheduledThreadPoolExecutor.shutdownNow()

java.util.concurrent.ScheduledThreadPoolExecutor.shutdownNow()
Attempts to stop all actively executing tasks, halts the processing of waiting tasks, and returns a list of the tasks that were awaiting execution.
This method does not wait for actively executing tasks to terminate. Use {@link #awaitTermination awaitTermination} todo that.
There are no guarantees beyond best-effort attempts to stop processing actively executing tasks. This implementation cancels tasks via {@link Thread#interrupt}, so any task that fails to respond to interrupts may never terminate. @return list of tasks that never commenced execution.Each element of this list is a {@link ScheduledFuture}, including those tasks submitted using {@code execute}, which are for scheduling purposes used as the basis of a zero-delay {@code ScheduledFuture}. @throws SecurityException {@inheritDoc}

    // Stop executor. It was only needed to poll AE initialization status.
    // Since deploy() completed
    // the UIMA AS service either succeeded initializing or it failed. In
    // either case we no longer
    // need to poll for initialization status
    executor.shutdownNow();


    if (serviceDeployer == null || serviceDeployer.initializationFailed()) {
      currentState = ProcessState.FailedInitialization;
      System.out
          .println(">>> Failed to Deploy UIMA Service. Check UIMA Log for Details");
