Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.

Usage

From source file:de.quist.samy.remocon.RemoteSession.java

private String initialize() throws UnknownHostException, IOException {
    logger.debug("Creating socket for host " + host + " on port " + port);

    socket = new Socket();
    socket.connect(new InetSocketAddress(host, port), 5000);

    logger.debug("Socket successfully created and connected");
    InetAddress localAddress = socket.getLocalAddress();
    logger.debug("Local address is " + localAddress.getHostAddress());

    logger.debug("Sending registration message");
    writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
    writer.append((char) 0x00);
    writeText(writer, APP_STRING);/*w  w  w.j  av  a  2  s. c  o m*/
    writeText(writer, getRegistrationPayload(localAddress.getHostAddress()));
    writer.flush();

    InputStream in = socket.getInputStream();
    reader = new InputStreamReader(in);
    String result = readRegistrationReply(reader);
    //sendPart2();
    int i;
    while ((i = in.available()) > 0) {
        in.skip(i);
