本文整理了Java中java.util.concurrent.ExecutorService.isTerminated()方法的一些代码示例,展示了ExecutorService.isTerminated()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。ExecutorService.isTerminated()方法的具体详情如下:
包路径:java.util.concurrent.ExecutorService
类名称:ExecutorService
方法名:isTerminated

ExecutorService.isTerminated介绍

[英]Returns true if all tasks have completed following shut down. Note that isTerminated is never true unless either shutdown or shutdownNow was called first.
[中]如果关闭后所有任务都已完成,则返回true。请注意,除非先调用shutdown或shutdownNow,否则isTerminated永远不会为true。

  } catch (InterruptedException e) {
   LOGGER.error("exception awaiting termination", e);
  }
 }
