Class `std.socket.Socket`

Socket is a class that creates a network communication endpoint using the Berkeley sockets interface.


						
				class Socket
				;

Constructors

Name	Description
`this`	Create a blocking socket. If a single protocol type exists to support this socket type within the address family, the `ProtocolType` may be omitted.
`this`	Create a blocking socket using the parameters from the specified `AddressInfo` structure.
`this`	Use an existing socket handle.

Fields

Name	Type	Description
`_blocking`	`bool`	Property to get or set whether the socket is blocking or nonblocking.

Properties

Name	Type	Description
`addressFamily`[get]	`AddressFamily`	Get the socket's address family.
`blocking`[get, set]	`bool`	Get/set socket's blocking flag.
`handle`[get]	`std.socket.socket_t`	Get underlying socket handle.
`hostName`[get]	`string`
`isAlive`[get]	`bool`	Property that indicates if this is a valid, alive socket.
`localAddress`[get]	`Address`	Local endpoint `Address`.
`remoteAddress`[get]	`Address`	Remote endpoint `Address`.

Methods

Name	Description
`accept`	Accept an incoming connection. If the socket is blocking, `accept` waits for a connection request. Throws `SocketAcceptException` if unable to accept. See `accepting` for use with derived classes.
`bind`	Associate a local address with this socket.
`close`	Immediately drop any connections and release socket resources. Calling `shutdown` before `close` is recommended for connection-oriented sockets. The `Socket` object is no longer usable after `close`. Calling shutdown() before this is recommended for connection-oriented sockets.
`connect`	Establish a connection. If the socket is blocking, connect waits for the connection to be made. If the socket is nonblocking, connect returns immediately and the connection attempt is still in progress.
`getErrorText`	Get a text description of this socket's error status, and clear the socket's error status.
`getOption`	Get a socket option.
`getOption`	Common case of getting integer and boolean options.
`getOption`	Get the linger option.
`getOption`	Get a timeout (duration) option.
`listen`	Listen for an incoming connection. `bind` must be called before you can `listen`. The `backlog` is a request of how many pending incoming connections are queued until `accept`ed.
`receive`	Receive data on the connection. If the socket is blocking, `receive` waits until there is data to be received.
`receiveFrom`	Receive data and get the remote endpoint `Address`. If the socket is blocking, `receiveFrom` waits until there is data to be received.
`select`	Wait for a socket to change status. A wait timeout of `Duration` or `TimeVal`, may be specified; if a timeout is not specified or the `TimeVal` is `null`, the maximum timeout is used. The `TimeVal` timeout has an unspecified value when `select` returns.
`send`	Send data on the connection. If the socket is blocking and there is no buffer space left, `send` waits.
`sendTo`	Send data to a specific destination Address. If the destination address is not specified, a connection must have been made and that address is used. If the socket is blocking and there is no buffer space left, `sendTo` waits.
`setKeepAlive`	Enables TCP keep-alive with the specified parameters.
`setOption`	Set a socket option.
`setOption`	Common case for setting integer and boolean options.
`setOption`	Set the linger option.
`setOption`	Sets a timeout (duration) option, i.e. `SocketOption.SNDTIMEO` or `RCVTIMEO`. Zero indicates no timeout.
`shutdown`	Disables sends and/or receives.
`factory`	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`opCmp`	Compare with another Object obj.
`opEquals`	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides for `opEquals` should attempt to compare objects by their contents.
`toHash`	Compute hash function for Object.
`toString`	Convert Object to a human readable string.
`accepting`	Called by `accept` when a new `Socket` must be created for a new connection. To use a derived class, override this method and return an instance of your class. The returned `Socket`'s handle must not be set; `Socket` has a protected constructor `this()` to use in this situation.
`createAddress`	Can be overridden to support other addresses.
