## Overview

An HTTP and WebSockets server.

You receive HTTP requests by providing a #request_handler. As requests arrive on the server the handler will be called with the requests.

You receive WebSockets by providing a #websocket_handler. As WebSocket connections arrive on the server, the WebSocket is passed to the handler.

## Instance Method Summary (collapse)

- - (Fixnum) actual_port
  The actual port the server is listening on.
- - (void) close { ... }
  Like #close but supplying a handler that will be called when the server is actually closed (or has failed).
- - (self) connection_handler { ... }
  Set a connection handler for the server.
- - (self) listen(port = nil, host = nil) { ... }
  Like #listen but supplying a handler that will be called when the server is actually listening (or has failed).
- - (true, false) metrics_enabled?
  Whether the metrics are enabled for this measured object.
- - (self) request_handler { ... }
  Set the request handler for the server to requestHandler.
- - (::Vertx::HttpServerRequestStream) request_stream
  Return the request stream for the server.
- - (self) websocket_handler { ... }
  Set the websocket handler for the server to wsHandler.
- - (::Vertx::ServerWebSocketStream) websocket_stream
  Return the websocket stream for the server.

## Instance Method Details

### - (`Fixnum`) actual_port

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:

- (`Fixnum`) —
  the actual port the server is listening on.

Raises:

- (`ArgumentError`)

        return @j_del.java_method(:actualPort, []).call()
      end
      raise ArgumentError, "Invalid arguments when calling actual_port()"
    end

### - (`void`) close { ... }

This method returns an undefined value.

Like #close but supplying a handler that will be called when the server is actually closed (or has failed).

Yields:

- the handler

Raises:

- (`ArgumentError`)

      end
      raise ArgumentError, "Invalid arguments when calling close()"
    end

### - (`self`) connection_handler { ... }

Set a connection handler for the server.

Yields:

Returns:

- (`self`)

Raises:

- (`ArgumentError`)

        return self
      end
      raise ArgumentError, "Invalid arguments when calling connection_handler()"
    end

### - (`self`) listen(port = nil, host = nil) { ... }

Like #listen but supplying a handler that will be called when the server is actually listening (or has failed).

Parameters:

- port (`Fixnum`) (defaults to: `nil`) —
  the port to listen on
- host (`String`) (defaults to: `nil`) —
  the host to listen on

Yields:

- the listen handler

Returns:

- (`self`)

Raises:

- (`ArgumentError`)
