Usage

From source file:org.gcaldaemon.core.ldap.LDAPListener.java

LDAPListener(ContactLoader loader, FilterMask[] hosts, FilterMask[] addresses, int port) throws Exception {

    // Starting server
    log.info("LDAP server starting on port " + port + "...");

    // Store pointers
    this.loader = loader;
    this.hosts = hosts;

    // Allocate an unbound server socket channel
    serverChannel = ServerSocketChannel.open();

    // Get the associated ServerSocket to bind it with
    ServerSocket serverSocket = serverChannel.socket();

    // Set the port the server channel will listen to
    serverSocket.bind(new InetSocketAddress(port));

    // Set non-blocking mode for the listening socket
    serverChannel.configureBlocking(false);

    // Create a new Selector for use below
