class sys.net.Socket
Available in neko, php, cpp, cs, java
A TCP socket class : allow you to both connect to a given server and exchange messages or start your own server and wait for connections.
var custom : Dynamic
A custom value that can be associated with the socket. Can be used to retreive your custom infos after a select.
var input(default,null) : haxe.io.Input
The stream on which you can read available data. By default the stream is blocking until the requested data is available, use setBlocking(false) or setTimeout to prevent infinite waiting.
var output(default,null) : haxe.io.Output
The stream on which you can send data. Please note that in case the output buffer you will block while writing the data, use setBlocking(false) or setTimeout to prevent that.
function new() : Void
Creates a new unconnected socket.
function accept() : Socket
Accept a new connected client. This will return a connected socket on which you can read/write some data.
function bind(host : Host, port : Int) : Void
Bind the socket to the given host/port so it can afterwards listen for connections there.
function close() : Void
Closes the socket : make sure to properly close all your sockets or you will crash when you run out of file descriptors.
function connect(host : Host, port : Int) : Void
Connect to the given server host/port. Throw an exception in case we couldn't sucessfully connect.
function host() : { port : Int, host : Host}
Return the informations about our side of a connected socket.
function listen(connections : Int) : Void
Allow the socket to listen for incoming questions. The parameter tells how many pending connections we can have until they get refused. Use accept() to accept incoming connections.
function peer() : { port : Int, host : Host}
Return the informations about the other side of a connected socket.
function read() : String
Read the whole data available on the socket.
function setBlocking(b : Bool) : Void
Change the blocking mode of the socket. A blocking socket is the default behavior. A non-blocking socket will abort blocking operations immediatly by throwing a haxe.io.Error.Blocking value.
function setFastSend(b : Bool) : Void
Allows the socket to immediatly send the data when written to its output : this will cause less ping but might increase the number of packets / data size, especially when doing a lot of small writes.
function setTimeout(timeout : Float) : Void
Gives a timeout after which blocking socket operations (such as reading and writing) will abort and throw an exception.
function shutdown(read : Bool, write : Bool) : Void
Shutdown the socket, either for reading or writing.
function waitForRead() : Void
Block until some data is available for read on the socket.
function write(content : String) : Void
Write the whole data to the socket output.
static function select(read : Array<Socket>, write : Array<Socket>, others : Array<Socket>, ?timeout : Float) : { write : Array<Socket>, read : Array<Socket>, others : Array<Socket>}
Wait until one of the sockets groups is ready for the given operation : read contains sockets on which we want to wait for available data to be read, write contains sockets on which we want to wait until we are allowed to write some data to their output buffers, others contains sockets on which we want to wait for exceptional conditions. select will block until one of the condition is met, in which case it will return the sockets for which the condition was true. In case a timeout (in seconds) is specified, select might wait at worse until the timeout expires.
