Document

Creates a new data output stream to write data to the specified underlying output stream.

Usage

From source file:com.maverick.ssl.SSLTransportImpl.java

public void initialize(InputStream in, OutputStream out, SSLContext context) throws IOException, SSLException {

    this.rawIn = new DataInputStream(in);
    this.rawOut = new DataOutputStream(out);
    writeCipherSuite = readCipherSuite = new SSL_NULL_WITH_NULL_NULL();

    // #ifdef DEBUG
    log.debug(Messages.getString("SSLTransport.initialising")); //$NON-NLS-1$
    // #endif/*from   w w w.  jav a2 s. c  om*/

    if (context == null)
        context = new SSLContext();

    handshake = new SSLHandshakeProtocol(this, context);

    // Start the handshake
    handshake.startHandshake();

    // While the handshake is not complete process all the messages
    while (!handshake.isComplete()) {
        processMessages();

        // #ifdef DEBUG
        log.debug(Messages.getString("SSLTransport.initCompleteStartingAppProtocol")); //$NON-NLS-1$
        // #endif
