Java Phaser bulkRegister() 方法

2025 年 3 月 21 日 | 阅读 2 分钟

bulkRegister() 方法是 Phaser 类的一部分。此方法将给定数量的新未到达的参与方添加到此 phaser 中。

语法

参数

parties - 这是在下一阶段预先添加的参与方数量。

它返回此注册适用的到达阶段的数量。

抛出

IllegalStateException - 如果尝试注册的参与方数量超过最大数量，则抛出此异常。

IllegalArgumentException - 如果 parties 小于 0，则抛出此异常。

示例 1

import java.util.concurrent.Phaser;
public class PhaserBulkRegisterExample1
{
    public static void main(String[] args) throws InterruptedException
    {
          Phaser p = new Phaser();
          p.register();
          int pc = p.getPhase();
          System.out.println("Phasecount is "+pc);
          
          for(int i=1; i<=5; i++)
          {
            new PhaserBulkRegisterExample1().test(p);
            System.out.println("Unarrived parties to current phaser : "+p.bulkRegister(2));
          } 
          Thread.sleep(5000);
          pc = p.getPhase();
          System.out.println("Phasecount is "+pc);
    }
    private void test(final Phaser phaser)
    {
        new Thread(){
                @Override
                public void run()
                    {
                        try{ 
                        System.out.println(Thread.currentThread().getName()+" arrived");
                       
                        }
                        catch(IllegalArgumentException e) 
                        {}
                    }
               }.start();
    }
}

输出

Phasecount is 0
Unarrived parties to current phaser : 0
Thread-0 arrived
Unarrived parties to current phaser : 0
Thread-1 arrived
Thread-2 arrived
Unarrived parties to current phaser : 0
Unarrived parties to current phaser : 0
Unarrived parties to current phaser : 0
Thread-4 arrived
Thread-3 arrived
Phasecount is 0

               System.out.println("Unarrived parties to current phaser : "+p.bulkRegister(0));
             new PhaserBulkRegisterExample2().test(p);
                System.out.println("Unarrived parties to current phaser : "+p.bulkRegister(1));
             
          Thread.sleep(5000);
          pc = p.getPhase();
          System.out.println("Phasecount is "+pc);
    }
    private void test(final Phaser phaser)
    {
        new Thread(){
                @Override
                public void run()
                    {
                        try{ 
                        System.out.println(Thread.currentThread().getName()+" arrived"); 
                        }
                        catch(IllegalArgumentException e) 
                        {}
                    }
               }.start();
    }
}

输出

Phasecount is 0
Unarrived parties to current phaser : 0
Unarrived parties to current phaser : 0
Thread-0 arrived
Thread-1 arrived
Phasecount is 0
