java中使用队列Queue

Lock queueLock = new ReentrantLock();

Queue<Frame> mFrameQueue = new LinkedList<Frame>();

入队

queueLock.lock();

while(true) {

Frame oFrame = (Frame)this.mFrameQueue.peek();

if (oFrame == null) {

break;

}

}

this.mFrameQueue.offer(frame);

queueLock.unlock();

出队

queueLock.lock();

Frame frame = (Frame)this.mFrameQueue.poll();

queueLock.unlock();
