class TLSSocket

Socket has the property that socket.write always works. This is to help users get up and running quickly. The computer cannot always keep up with the amount of data that is written to a socket - the network connection simply might be too slow. Node will internally queue up the data written to a socket and send it out over the wire when it is possible. (Internally it is polling on the socket's file descriptor for being writable).

The consequence of this internal buffering is that memory may grow. This property shows the number of characters currently buffered to be written. (Number of characters is approximately equal to the number of bytes to be written, but the buffer may contain strings, and the strings are lazily encoded, so the exact number of bytes is not known.)

Users who experience large or growing bufferSize should attempt to "throttle" the data flows in their program with pause and resume.

The amount of received bytes.

The amount of bytes sent.

Always true for TLSSocket instances.

May be used to distinguish TLS sockets from regular ones.

The string representation of the local IP address the remote client is connecting on. For example, if you are listening on '0.0.0.0' and the client connects on '192.168.1.1', the value would be '192.168.1.1'.

The numeric representation of the local port. For example, 80 or 21.

The string representation of the remote IP address. For example, '74.125.127.100' or '2001:4860:a005::68'.

The string representation of the remote IP family. 'IPv4' or 'IPv6'.

The numeric representation of the remote port. For example, 80 or 21.

Is true if it is safe to call writable.write().

Is true after writable.end() has been called. This property does not indicate whether the data has been flushed, for this use writable.writableFinished instead.

See also:

• https://nodejs.org/api/stream.html#stream_writable_writableended

Is set to true immediately before the 'finish' event is emitted.

See also:

• https://nodejs.org/api/stream.html#stream_writable_writablefinished

This property contains the number of bytes (or objects) in the queue ready to be written. The value provides introspection data regarding the status of the highWaterMark.

See also:

• https://nodejs.org/api/stream.html#stream_writable_writablelength

Getter for the property objectMode of a given Writable stream.

See also:

• https://nodejs.org/api/stream.html#stream_writable_writableobjectmode

Return the value of highWaterMark passed when constructing this Writable.

See also:

• https://nodejs.org/api/stream.html#stream_writable_writablehighwatermark

Is true after readable.destroy() has been called.

See also:

• https://nodejs.org/api/stream.html#stream_readable_destroyed

Terminal read streams (i.e. process.stdin) have this property set to true. It is false for any other read streams.

See also:

• https://nodejs.org/api/tty.html#tty_readstream_istty

Is true if it is safe to call readable.read().

See also:

• https://nodejs.org/api/stream.html#stream_readable_readable

Getter for the property encoding of a given Readable stream. The encoding property can be set using the readable.setEncoding() method.

See also:

• https://nodejs.org/api/stream.html#stream_readable_readableencoding

Becomes true when 'end' event is emitted.

See also:

• https://nodejs.org/api/stream.html#stream_readable_readableended

Returns the value of highWaterMark passed when constructing this Readable.

See also:

• https://nodejs.org/api/stream.html#stream_readable_readablehighwatermark

This property contains the number of bytes (or objects) in the queue ready to be read. The value provides introspection data regarding the status of the highWaterMark.

See also:

• https://nodejs.org/api/stream.html#stream_readable_readablelength

Getter for the property objectMode of a given Readable stream.

See also:

• https://nodejs.org/api/stream.html#stream_readable_readableobjectmode

Returns the bound address, the address family name and port of the socket as reported by the operating system.

Opens the connection for a given socket.

If port and host are given, then the socket will be opened as a TCP socket, if host is omitted, localhost will be assumed. If a path is given, the socket will be opened as a unix socket to that path.

Normally this method is not needed, as Net.createConnection opens the socket. Use this only if you are implementing a custom Socket.

This function is asynchronous. When the 'connect' event is emitted the socket is established. If there is a problem connecting, the 'connect' event will not be emitted, the 'error' event will be emitted with the exception

The connectListener parameter will be added as an listener for the 'connect' event.

A boolean value that indicates if the connection is destroyed or not. Once a connection is destroyed no further data can be transferred using it.

define in Stream/Readable.hx

Opposite of unref, calling ref on a previously unrefd socket will not let the program exit if it's the only socket left (the default behavior). If the socket is refd calling ref again will have no effect.

Enable/disable keep-alive functionality, and optionally set the initial delay before the first keepalive probe is sent on an idle socket.

enable defaults to false.

Set initialDelay (in milliseconds) to set the delay between the last data packet received and the first keepalive probe.

Setting 0 for initialDelay will leave the value unchanged from the default (or previous) setting. Defaults to 0.

Disables the Nagle algorithm. By default TCP connections use the Nagle algorithm, they buffer data before sending it off. Setting true for noDelay will immediately fire off data each time write is called. noDelay defaults to true.

Sets the socket to timeout after timeout milliseconds of inactivity on the socket. By default Socket do not have a timeout.

When an idle timeout is triggered the socket will receive a 'timeout' event but the connection will not be severed. The user must manually end or destroy the socket.

If timeout is 0, then the existing idle timeout is disabled.

The optional callback parameter will be added as a one time listener for the 'timeout' event.

Calling unref on a socket will allow the program to exit if this is the only active socket in the event system. If the socket is already unrefd calling unref again will have no effect.

The writable.cork() method forces all written data to be buffered in memory. The buffered data will be flushed when either the stream.uncork() or stream.end() methods are called.

See also:

• https://nodejs.org/api/stream.html#stream_writable_cork

Calling the writable.end() method signals that no more data will be written to the Writable. The optional chunk and encoding arguments allow one final additional chunk of data to be written immediately before closing the stream. If provided, the optional callback function is attached as a listener for the 'finish' event.

See also:

• https://nodejs.org/api/stream.html#stream_writable_end_chunk_encoding_callback

The writable.setDefaultEncoding() method sets the default encoding for a Writable stream.

See also:

• https://nodejs.org/api/stream.html#stream_writable_setdefaultencoding_encoding

The writable.uncork() method flushes all data buffered since stream.cork() was called.

See also:

• https://nodejs.org/api/stream.html#stream_writable_uncork

The writable.write() method writes some data to the stream, and calls the supplied callback once the data has been fully handled. If an error occurs, the callback may or may not be called with the error as its first argument. To reliably detect write errors, add a listener for the 'error' event.

• https://nodejs.org/api/stream.html#stream_writable_write_chunk_encoding_callback

The readable.isPaused() method returns the current operating state of the Readable. This is used primarily by the mechanism that underlies the readable.pipe() method. In most typical cases, there will be no reason to use this method directly.

See also:

• https://nodejs.org/api/stream.html#stream_readable_ispaused

The readable.pause() method will cause a stream in flowing mode to stop emitting 'data' events, switching out of flowing mode. Any data that becomes available will remain in the internal buffer.

See also:

• https://nodejs.org/api/stream.html#stream_readable_pause

The readable.pipe() method attaches a Writable stream to the readable, causing it to switch automatically into flowing mode and push all of its data to the attached Writable. The flow of data will be automatically managed so that the destination Writable stream is not overwhelmed by a faster Readable stream.

See also:

• https://nodejs.org/api/stream.html#stream_readable_pipe_destination_options

The readable.read() method pulls some data out of the internal buffer and returns it. If no data available to be read, null is returned. By default, the data will be returned as a Buffer object unless an encoding has been specified using the readable.setEncoding() method or the stream is operating in object mode.

See also:

• https://nodejs.org/api/stream.html#stream_readable_read_size

The readable.resume() method causes an explicitly paused Readable stream to resume emitting 'data' events, switching the stream into flowing mode.

See also:

• https://nodejs.org/api/stream.html#stream_readable_resume

The readable.setEncoding() method sets the character encoding for data read from the Readable stream.

See also:

• https://nodejs.org/api/stream.html#stream_readable_setencoding_encoding

The readable.unpipe() method detaches a Writable stream previously attached using the stream.pipe() method.

See also:

• https://nodejs.org/api/stream.html#stream_readable_unpipe_destination

Passing chunk as null signals the end of the stream (EOF), after which no more data can be written.

See also:

• https://nodejs.org/api/stream.html#stream_readable_unshift_chunk_encoding

Prior to Node.js 0.10, streams did not implement the entire stream module API as it is currently defined. (See Compatibility for more information.)

Returns an array listing the events for which the emitter has registered listeners. The values in the array will be strings or Symbols.

See also:

• https://nodejs.org/api/events.html#events_emitter_eventnames

Returns the current max listener value for the EventEmitter which is either set by emitter.setMaxListeners(n) or defaults to EventEmitter.defaultMaxListeners.

Adds the listener function to the end of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

See also:

• https://nodejs.org/api/events.html#events_emitter_on_eventname_listener

Adds a one-time listener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

See also:

• https://nodejs.org/api/events.html#events_emitter_once_eventname_listener

Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

See also:

• https://nodejs.org/api/events.html#events_emitter_prependlistener_eventname_listener

Adds a one-time listener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

See also:

• https://nodejs.org/api/events.html#events_emitter_prependoncelistener_eventname_listener

Returns a copy of the array of listeners for the event named eventName, including any wrappers (such as those created by .once()).

See also:

• https://nodejs.org/api/events.html#events_emitter_rawlisteners_eventname

• https://nodejs.org/api/events.html#events_emitter_removelistener_eventname_listener

By default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default that helps finding memory leaks. Obviously, not all events should be limited to just 10 listeners. The emitter.setMaxListeners() method allows the limit to be modified for this specific EventEmitter instance. The value can be set to Infinity (or 0) to indicate an unlimited number of listeners.
