 * Simple alternative to JDK {@link java.io.PipedOutputStream}; queue input stream provides what's written in queue
 * output stream.
 * <p>
 * Example usage:
 * </p>
 * <pre>
 * QueueOutputStream outputStream = new QueueOutputStream();
 * QueueInputStream inputStream = outputStream.newPipeInputStream();
 * outputStream.write("hello world".getBytes(UTF_8));
 * inputStream.read();
 * </pre>
 * Unlike JDK {@link PipedInputStream} and {@link PipedOutputStream}, queue input/output streams may be used safely in a
 * single thread or multiple threads. Also, unlike JDK classes, no special meaning is attached to initial or current
 * thread. Instances can be used longer after initial threads exited.
 * <p>
 * Closing a {@code QueueOutputStream} has no effect. The methods in this class can be called after the stream has been
 * closed without generating an {@code IOException}.
 * </p>
 * @see QueueInputStream
 * @since 2.9.0
public class QueueOutputStream extends OutputStream {

    private final BlockingQueue<Integer> blockingQueue;

     * Constructs a new instance with no limit to internal buffer size.
    public QueueOutputStream() {
        this(new LinkedBlockingQueue<>());

     * Constructs a new instance with given buffer.
     * @param blockingQueue backing queue for the stream
    public QueueOutputStream(final BlockingQueue<Integer> blockingQueue) {
        this.blockingQueue = Objects.requireNonNull(blockingQueue, "blockingQueue");

     * Creates a new QueueInputStream instance connected to this. Writes to this output stream will be visible to the
     * input stream.
     * @return QueueInputStream connected to this stream
    public QueueInputStream newQueueInputStream() {
        return new QueueInputStream(blockingQueue);

     * Writes a single byte.
     * @throws InterruptedIOException if the thread is interrupted while writing to the queue.
    public void write(final int b) throws InterruptedIOException {
        try {
            blockingQueue.put(0xFF & b);
        } catch (final InterruptedException e) {
            final InterruptedIOException interruptedIoException = new InterruptedIOException();
            throw interruptedIoException;
