此方法在ScheduledThreadPoolExecutor中声明。
/**
* Sets the policy on whether cancelled tasks should be immediately
* removed from the work queue at time of cancellation. This value is
* by default {@code false}.
*
* @param value if {@code true}, remove on cancellation, else don't
* @see #getRemoveOnCancelPolicy
* @since 1.7
*/
public void setRemoveOnCancelPolicy(boolean value) {
removeOnCancel = value;
}
Executors类通过newScheduledThreadPool和类似方法返回此执行程序。
public static scheduledexecutorservice newScheduledThreadPool(int corePoolSize) {
return new ScheduledThreadPoolExecutor(corePoolSize);
}
ScheduledThreadPoolExecutor ex = (ScheduledThreadPoolExecutor) Executors.newScheduledThreadPool(5);
ex.setRemoveOnCancelPolicy(true);
或new ScheduledThreadPoolExecutor自己创建。
ScheduledThreadPoolExecutor ex = new ScheduledThreadPoolExecutor(5);
ex.setRemoveOnCancelPolicy(true);
