Defined in:

## Overview

Represents a socket-like interface to a TCP connection on either the client or the server side.

Instances of this class are created on the client side by an NetClient when a connection to a server is made, or on the server side by a NetServer when a server accepts a connection.

It implements both and so it can be used with Pump to pump data with flow control.

## Instance Method Summary (collapse)

- - (void) close { ... }
  Close the NetSocket and notify the handler when the operation completes.
- - (self) close_handler { ... }
  Set a handler that will be called when the NetSocket is closed.
- - (self) drain_handler { ... }
- - (void) end(data = nil) { ... }
  Same as but with an handler called when the operation completes.
- - (self) end_handler { ... }
  This handler might be called after the close handler when the socket is paused and there are still buffers to deliver.
- - (self) exception_handler { ... }
- - (self) fetch(amount = nil)
- - (self) handler { ... }
- - (String) indicated_server_name
  Returns the SNI server name presented during the SSL handshake by the client.
- - (::Vertx::SocketAddress) local_address
  The local address for this socket.
- - (self) pause
- - (::Vertx::Pipe) pipe
  Pause this stream and return a to transfer the elements of this stream to a destination .
- - (void) pipe_to(dst = nil) { ... }
  Pipe this ReadStream to the WriteStream.
- - (::Vertx::SocketAddress) remote_address
  The remote address for this socket.
- - (self) resume
- - (self) send_file(filename = nil, offset = nil, length = nil) { ... }
  Same as #send_file but also takes a handler that will be called when the send has completed or a failure has occurred.
- - (self) set_write_queue_max_size(maxSize = nil)
- - (true, false) ssl?
  True if this NetSocket is encrypted via SSL/TLS.
- - (self) upgrade_to_ssl(serverName = nil) { ... }
  Upgrade channel to use SSL/TLS.
- - (self) write(param_1 = nil, param_2 = nil)
  Same as #write but with an handler called when the operation completes.
- - (String) write_handler_id
  When a NetSocket is created it automatically registers an event handler with the event bus, the ID of that handler is given by writeHandlerID.
- - (true, false) write_queue_full?
  This will return true if there are more bytes in the write queue than the value set using #set_write_queue_max_size.

### - (`self`) write(data) - (`self`) write(str) - (`self`) write(str, handler) { ... } - (`self`) write(str, enc) - (`self`) write(message, handler) { ... } - (`self`) write(str, enc, handler) { ... }

Same as #write but with an `handler` called when the operation completes

Overloads:

- - (`self`) write(data)

  Parameters:

  - data (`::Vertx::Buffer`)
- - (`self`) write(str)

  Parameters:

  - str (`String`) —
    the string to write
- - (`self`) write(str, handler) { ... }

  Parameters:

  - str (`String`)

  Yields:

- - (`self`) write(str, enc)

  Parameters:

  - str (`String`) —
    the string to write
  - enc (`String`) —
    the encoding to use
- - (`self`) write(message, handler) { ... }

  Parameters:

  - message (`::Vertx::Buffer`)

  Yields:

- - (`self`) write(str, enc, handler) { ... }

  Parameters:

  - str (`String`)
  - enc (`String`)

  Yields:

Returns:

- (`self`)

Raises:

- (`ArgumentError`)

### - (`String`) write_handler_id

When a `NetSocket` is created it automatically registers an event handler with the event bus, the ID of that handler is given by `writeHandlerID`.

Given this ID, a different event loop can send a buffer to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other connections which are owned by different event loops.

Returns:

- (`String`) —
  the write handler ID

Raises:

- (`ArgumentError`)

### - (`true`, `false`) write_queue_full?

This will return `true` if there are more bytes in the write queue than the value set using #set_write_queue_max_size

Returns:

- (`true`, `false`) —
  true if write queue is full

Raises:

- (`ArgumentError`)
