java Queue processing
Example code:
import java.util.LinkedList;
import java.util.Queue;
private static Queue<FrameStruct> frameQueue = new LinkedList<FrameStruct>();
private static Lock lock = new ReentrantLock();
private PlayerThread p = new PlayerThread();
Fetch data from the queue for processing:
private class PlayerThread extends Thread {
@Override
public void run() {
FrameStruct frame;
while(bPlayRun)
{
if(bCanFlush)
{
lock.lock();
while((frame=frameQueue.poll())!=null)
{
onFrame(frame.buf, 0, frame.len);
try {
Thread.sleep(30);
} catch (InterruptedException e) {
}
}
lock.unlock();
}
}
}
}
Another thread puts the data into the queue:
FrameStruct frame = new FrameStruct();
frame.buf = new byte[byteCount];
frame.len = byteCount;
System.arraycopy(frameData, 0, frame.buf, 0, byteCount);
lock.lock();
frameQueue.offer(frame);
lock.unlock();
