class Socket

package sys.net

extended by SslSocket, Socket, SslSocket, UdpSocket, Socket

@:coreApi

Available on cpp, php, macro, jvm, hl, neko, lua, python

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.

Static methods

@:keepstaticselect(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 group 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 worst until the timeout expires.

Constructor

@:keepnew()

Creates a new unconnected socket.

Variables

@:keepcustom:Dynamic

Available on cpp, php, macro, jvm, hl, neko, python

A custom value that can be associated with the socket. Can be used to retrieve your custom infos after a select.

@:keepread onlyinput: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.

@:keepread onlyoutput: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.

Methods

@:keepaccept():Socket

Accept a new connected client. This will return a connected socket on which you can read/write some data.

@:keepbind(host:Host, port:Int):Void

Bind the socket to the given host/port so it can afterwards listen for connections there.

@:has_untyped@:keepclose():Void

Closes the socket : make sure to properly close all your sockets or you will crash when you run out of file descriptors.

@:keepconnect(host:Host, port:Int):Void

Connect to the given server host/port. Throw an exception in case we couldn't successfully connect.

@:has_untyped@:keephost():{port:Int, host:Host}

Return the information about our side of a connected socket.

@:keeplisten(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.

@:has_untyped@:keeppeer():{port:Int, host:Host}

Return the information about the other side of a connected socket.

@:keepread():String

Read the whole data available on the socket.

Note: this is not meant to be used together with setBlocking(false), as it will always throw haxe.io.Error.Blocked. input methods should be used directly instead.

@:keepsetBlocking(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 immediately by throwing a haxe.io.Error.Blocked value.

@:keepsetFastSend(b:Bool):Void

Allows the socket to immediately 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.

@:keepsetTimeout(timeout:Float):Void

Gives a timeout (in seconds) after which blocking socket operations (such as reading and writing) will abort and throw an exception.

@:keepshutdown(read:Bool, write:Bool):Void

Shutdown the socket, either for reading or writing.

@:keepwaitForRead():Void

Block until some data is available for read on the socket.

@:keepwrite(content:String):Void

Write the whole data to the socket output.

Note: this is not meant to be used together with setBlocking(false), as haxe.io.Error.Blocked may be thrown mid-write with no indication of how many bytes have been written. output.writeBytes() should be used instead as it returns this information.
