- Method Detail
  - connectStream
```
ReadStream<NetSocket> 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
```
Future<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 future completed with the listen operation result
  - listen
```
default 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
```
default Future<NetServer> listen(int port,
                                 String host)
```
    Start listening on the specified port and host, ignoring port 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 future completed with the listen operation result
  - listen
```
default 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
```
default Future<NetServer> listen(int port)
```
    Start listening on the specified port and host "0.0.0.0", ignoring port 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 future completed with the listen operation result

    Parameters:
    
    completionHandler - the handler

```
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.
  - updateSSLOptions
```
Future<Void> updateSSLOptions(SSLOptions options)
