  • Method Details

    • terminated

      protected void terminated()
      Overrides:
      terminated in class java.util.concurrent.ThreadPoolExecutor

    • execute

      public void execute​(java.lang.Runnable command)
      Specified by:
      execute in interface java.util.concurrent.Executor
      Overrides:
      execute in class java.util.concurrent.ThreadPoolExecutor

    • afterExecute

      protected void afterExecute​(java.lang.Runnable r, java.lang.Throwable t)
      Overrides:
      afterExecute in class java.util.concurrent.ThreadPoolExecutor

    • getTasks

      public java.util.stream.Stream<java.lang.Runnable> getTasks()
      Returns a stream of all pending tasks. This is similar to ThreadPoolExecutor.getQueue() but will expose the originally submitted Runnable instances rather than potentially wrapped ones.

    • toString

      public final java.lang.String toString()
      Overrides:
      toString in class java.util.concurrent.ThreadPoolExecutor

    • appendThreadPoolExecutorDetails

      protected void appendThreadPoolExecutorDetails​(java.lang.StringBuilder sb)
      Append details about this thread pool to the specified StringBuilder. All details should be appended as key/value pairs in the form "%s = %s, "
      Parameters:
      sb - the StringBuilder to append to

    • wrapRunnable

      protected java.lang.Runnable wrapRunnable​(java.lang.Runnable command)

    • unwrap

      protected java.lang.Runnable unwrap​(java.lang.Runnable runnable)
