- - ### Method Detail

    - #### connectStream

          NetSocketStream connectStream()

      Return the connect stream for this server. The server can only have at most one handler at any one time. As the server accepts TCP or SSL connections it creates an instance of `NetSocket` and passes it to the connect stream `ReadStream.handler(io.vertx.core.Handler)`.
      Returns:
        the connect stream

    - #### connectHandler

          NetServer connectHandler(Handler<NetSocket> handler)

      Supply a connect handler for this server. The server can only have at most one connect handler at any one time. As the server accepts TCP or SSL connections it creates an instance of `NetSocket` and passes it to the connect handler.
      Returns:
        a reference to this, so the API can be used fluently

    - #### connectHandler

          Handler<NetSocket> connectHandler()

    - #### listen

          NetServer listen()

      Start listening on the port and host as configured in the `NetServerOptions` used when creating the server.

      The server may not be listening until some time after the call to listen has returned.

      Returns:
        a reference to this, so the API can be used fluently

    - #### listen

          NetServer listen(Handler<AsyncResult<NetServer>> listenHandler)

      Like `listen()` but providing a handler that will be notified when the server is listening, or fails.
      Parameters:
        `listenHandler` - handler that will be notified when listening or failed
      Returns:
        a reference to this, so the API can be used fluently

    - #### listen

          NetServer listen(int port,
                           String host)

      Start listening on the specified port and host, ignoring post and host configured in the `NetServerOptions` used when creating the server.

      Port `0` can be specified meaning "choose an random port".

      Host `0.0.0.0` can be specified meaning "listen on all available interfaces".

      The server may not be listening until some time after the call to listen has returned.

      Returns:
        a reference to this, so the API can be used fluently

    - #### listen

          NetServer listen(int port,
                           String host,
                           Handler<AsyncResult<NetServer>> listenHandler)

      Like `listen(int, String)` but providing a handler that will be notified when the server is listening, or fails.
      Parameters:
        `port` - the port to listen on
        `host` - the host to listen on
        `listenHandler` - handler that will be notified when listening or failed
      Returns:
        a reference to this, so the API can be used fluently

    - #### listen

          NetServer listen(int port)

      Start listening on the specified port and host "0.0.0.0", ignoring post and host configured in the `NetServerOptions` used when creating the server.

      Port `0` can be specified meaning "choose an random port".

      The server may not be listening until some time after the call to listen has returned.

      Returns:
        a reference to this, so the API can be used fluently

    - #### listen

          NetServer listen(int port,
                           Handler<AsyncResult<NetServer>> listenHandler)

      Like `listen(int)` but providing a handler that will be notified when the server is listening, or fails.
      Parameters:
        `port` - the port to listen on
        `listenHandler` - handler that will be notified when listening or failed
      Returns:
        a reference to this, so the API can be used fluently

    - #### close

          void close()

      Close the server. This will close any currently open connections. The close may not complete until after this method has returned.

    - #### close

          void close(Handler<AsyncResult<Void>> completionHandler)

      Like `close()` but supplying a handler that will be notified when close is complete.
      Parameters:
        `completionHandler` - the handler

    - #### actualPort

          int actualPort()

      The actual port the server is listening on. This is useful if you bound the server specifying 0 as port number signifying an ephemeral port
      Returns:
        the actual port the server is listening on.
