我有一个类,它从BlockingQueue
获取对象并通过连续调用take()
方法处理它们。在某个时刻,我知道不会再往队列中添加更多的对象了。那么,如何中断take()
方法以停止阻塞呢?
这是处理对象的类:
public class MyObjHandler implements Runnable {
private final BlockingQueue<MyObj> queue;
public class MyObjHandler(BlockingQueue queue) {
this.queue = queue;
}
public void run() {
try {
while (true) {
MyObj obj = queue.take();
// process obj here
// ...
}
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}
}
这里是使用这个类来处理对象的方法:
public void testHandler() {
BlockingQueue<MyObj> queue = new ArrayBlockingQueue<MyObj>(100);
MyObjectHandler handler = new MyObjectHandler(queue);
new Thread(handler).start();
// get objects for handler to process
for (Iterator<MyObj> i = getMyObjIterator(); i.hasNext(); ) {
queue.put(i.next());
}
// what code should go here to tell the handler
// to stop waiting for more objects?
}
