问题描述
例如：
new Thread(new Runnable() {
public void run() {
while(condition) {
*code that must not be interrupted*
*some more code*
}
}
}).start();
SomeOtherThread.start();
YetAntherThread.start();
如何确保不得中断的代码不会被打断了？
How can you ensure that code that must not be interrupted won't be interrupted?
推荐答案
你不能 - 至少不能使用普通的Java，正常，非实时运行操作系统。即使其他线程不打断你的，其他进程也可能会这样做。基本上，在完成之前，您将无法保证自己获得CPU。如果你想要这种保证，你应该使用像Java Real-Time System这样的东西。我不知道它是否肯定会提供你想要的设施。
You can't - at least not with normal Java, running on a normal, non-real-time operating system. Even if other threads don't interrupt yours, other processes might well do so. Basically you won't be able to guarantee that you get a CPU all to yourself until you're done. If you want this sort of guarantee you should use something like Java Real-Time System. I don't know enough about it to know whether that would definitely provide the facility you want though.
最好的要做的事情就是避免这个要求首先。
The best thing to do is avoid that requirement in the first place.
