AbstractQueuedSynchronizer之parkAndCheckInterrupt函數

函數parkAndCheckInterrupt()阻塞調用着線程，返回時，將指示是否因為中斷而返回！

private final boolean parkAndCheckInterrupt() {
        LockSupport.park(this);
        return Thread.interrupted();
    }

測試代碼:

import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.LockSupport;

public class ParkAndCheckInterrupt {

    private  final boolean parkAndCheckInterrupt() {
        LockSupport.park(this);
        return Thread.interrupted();
    }


    public static void main(String[] args) throws InterruptedException {
        ParkAndCheckInterrupt SPCK = new ParkAndCheckInterrupt();
        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                System.out.println("Before Park!");
                if (SPCK.parkAndCheckInterrupt()) {
                    System.out.println("中斷返回!");

                }else {
                    System.out.println("Unpark返回!");
                }
            }
        });

        thread.start();
        TimeUnit.SECONDS.sleep(1);
        thread.interrupt();
　　　　　//LockSupport.unpark(thread);

　　 } 
}
