public class DefaultAsyncJobExecutor extends Object implements AsyncExecutor

  • Field Details

    • corePoolSize

      protected int corePoolSize
      The minimal number of threads that are kept alive in the threadpool for job execution

    • maxPoolSize

      protected int maxPoolSize
      The maximum number of threads that are kept alive in the threadpool for job execution

    • keepAliveTime

      protected long keepAliveTime
      The time (in milliseconds) a thread used for job execution must be kept alive before it is destroyed. Default setting is 0. Having a non-default setting of 0 takes resources, but in the case of many job executions it avoids creating new threads all the time.

    • queueSize

      protected int queueSize
      The size of the queue on which jobs to be executed are placed

    • threadPoolQueue

      protected BlockingQueue<Runnable> threadPoolQueue
      The queue used for job execution work

    • executorService

      protected ExecutorService executorService
      The executor service used for job execution

    • secondsToWaitOnShutdown

      protected long secondsToWaitOnShutdown
      The time (in seconds) that is waited to gracefully shut down the threadpool used for job execution
