 * Simple alternative to JDK {@link java.io.PipedInputStream}; queue input stream provides what's written in queue
 * output stream.
 * <p>
 * Example usage:
 * </p>
 * <pre>
 * QueueInputStream inputStream = new QueueInputStream();
 * QueueOutputStream outputStream = inputStream.newQueueOutputStream();
 * outputStream.write("hello world".getBytes(UTF_8));
 * inputStream.read();
 * </pre>
 * <p>
 * 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>
 * <p>
 * Closing a {@code QueueInputStream} has no effect. The methods in this class can be called after the stream has been
 * closed without generating an {@code IOException}.
 * </p>
 * @see QueueOutputStream
 * @since 2.9.0
public class QueueInputStream extends InputStream {

    private final BlockingQueue<Integer> blockingQueue;

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

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

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

     * Reads and returns a single byte.
     * @return either the byte read or {@code -1} if the end of the stream has been reached
    public int read() {
        final Integer value = blockingQueue.poll();
        return value == null ? EOF : ((0xFF) & value);
