openfl.net.Socket - OpenFL API Reference

The Socket class enables code to establish Transport Control Protocol (TCP) socket connections for sending and receiving binary data. The Socket class is useful for working with servers that use binary protocols.

To use the methods of the Socket class, first use the constructor, new Socket, to create a Socket object.

A socket transmits and receives data asynchronously.

OpenFL target support: This feature is supported on all desktop operating systems, on iOS, and on Android. On the html5 target, it uses web sockets instead of raw unix-style sockets.

On some operating systems, flush() is called automatically between execution frames, but on other operating systems, such as Windows, the data is never sent unless you call flush() explicitly. To ensure your application behaves reliably across all operating systems, it is a good practice to call the flush() method after writing each message (or related group of data) to the socket.

In Adobe AIR, Socket objects are also created when a listening ServerSocket receives a connection from an external process. The Socket representing the connection is dispatched in a ServerSocketConnectEvent. Your application is responsible for maintaining a reference to this Socket object. If you don't, the Socket object is eligible for garbage collection and may be destroyed by the runtime without warning.

SWF content running in the local-with-filesystem security sandbox cannot use sockets.

Socket policy files on the target host specify the hosts from which SWF files can make socket connections, and the ports to which those connections can be made. The security requirements with regard to socket policy files have become more stringent in the last several releases of Flash Player. In all versions of Flash Player, Adobe recommends the use of a socket policy file; in some circumstances, a socket policy file is required. Therefore, if you are using Socket objects, make sure that the target host provides a socket policy file if necessary.

The following list summarizes the requirements for socket policy files in different versions of Flash Player:

In Flash Player 9.0.124.0 and later, a socket policy file is required for any socket connection. That is, a socket policy file on the target host is required no matter what port you are connecting to, and is required even if you are connecting to a port on the same host that is serving the SWF file.
In Flash Player versions 9.0.115.0 and earlier, if you want to connect to a port number below 1024, or if you want to connect to a host other than the one serving the SWF file, a socket policy file on the target host is required.
In Flash Player 9.0.115.0, even if a socket policy file isn't required, a warning is displayed when using the Flash Debug Player if the target host doesn't serve a socket policy file.
In AIR, a socket policy file is not required for content running in the application security sandbox. Socket policy files are required for any socket connection established by content running outside the AIR application security sandbox.

Events:

`close`	Dispatched when the server closes the socket connection. The `close` event is dispatched only when the server closes the connection; it is not dispatched when you call the `Socket.close()` method.
`connect`	Dispatched when a network connection has been established.
`ioError`	Dispatched when an input/output error occurs that causes a send or load operation to fail.
`securityError`	Dispatched if a call to `Socket.connect()` attempts to connect to a server prohibited by the caller's security sandbox or to a port lower than 1024 and no socket policy file exists to permit such a connection. Note: In an AIR application, content running in the application security sandbox is permitted to connect to any server and port number without a socket policy file.
`socketData`	Dispatched when a socket has received data. The data received by the socket remains in the socket until it is read. You do not have to read all the available data during the handler for this event. Events of type `socketData` do not use the `ProgressEvent.bytesTotal` property.

Constructor

`@:value({ port : 0, host : null })new(?host:String, port:Int = 0)`

Creates a new Socket object. If no parameters are specified, an initially disconnected socket is created. If parameters are specified, a connection is attempted to the specified host and port. Note: It is strongly advised to use the constructor form without parameters, then add any event listeners, then call the connect method with host and port parameters. This sequence guarantees that all event listeners will work properly.

Parameters:

`host`	A fully qualified DNS domain name or an IP address. IPv4 addresses are specified in dot-decimal notation, such as 192.0.2.0. In Flash Player 9.0.115.0 and AIR 1.0 and later, you can specify IPv6 addresses using hexadecimal-colon notation, such as 2001:db8:ccc3:ffff:0:444d:555e:666f. You can also specify `null` to connect to the host server on which the SWF file resides. If the SWF file issuing this call is running in a web browser, `host` must be in the domain from which the SWF file originated.
`port`	The TCP port number on the target host used to establish a connection. In Flash Player 9.0.124.0 and later, the target host must serve a socket policy file specifying that socket connections are permitted from the host serving the SWF file to the specified port. In earlier versions of Flash Player, a socket policy file is required only if you want to connect to a port number below 1024, or if you want to connect to a host other than the one serving the SWF file.

host

A fully qualified DNS domain name or an IP address. IPv4 addresses are specified in dot-decimal notation, such as 192.0.2.0. In Flash Player 9.0.115.0 and AIR 1.0 and later, you can specify IPv6 addresses using hexadecimal-colon notation, such as 2001:db8:ccc3:ffff:0:444d:555e:666f. You can also specify null to connect to the host server on which the SWF file resides. If the SWF file issuing this call is running in a web browser, host must be in the domain from which the SWF file originated.

port

The TCP port number on the target host used to establish a connection. In Flash Player 9.0.124.0 and later, the target host must serve a socket policy file specifying that socket connections are permitted from the host serving the SWF file to the specified port. In earlier versions of Flash Player, a socket policy file is required only if you want to connect to a port number below 1024, or if you want to connect to a host other than the one serving the SWF file.

Throws:

`SecurityError`	This error occurs in SWF content for the following reasons: Local-with-filesystem files cannot communicate with the Internet. You can work around this problem by reclassifying this SWF file as local-with-networking or trusted. This limitation is not set for AIR application content in the application security sandbox. You cannot specify a socket port higher than 65535.

Events:

`connect`	Dispatched when a network connection has been established.
`ioError`	Dispatched when an input/output error occurs that causes the connection to fail.
`securityError`	Dispatched if a call to `Socket.connect()` attempts to connect either to a server that doesn't serve a socket policy file, or to a server whose policy file doesn't grant the calling host access to the specified port. For more information on policy files, see "Website controls (policy files)" in the OpenFL Developer's Guide and the Flash Player Developer Center Topic: <a href="http://www.adobe.com/go/devnet_security_en" scope="external">Security.

Variables

`read onlybytesAvailable:Int`

The number of bytes of data available for reading in the input buffer.

Your code must access bytesAvailable to ensure that sufficient data is available before trying to read it with one of the read methods.

`read onlybytesPending:Int`

Indicates the number of bytes remaining in the write buffer.

Use this property in combination with with the OutputProgressEvent. An OutputProgressEvent is thrown whenever data is written from the write buffer to the network. In the event handler, you can check bytesPending to see how much data is still left in the buffer waiting to be written. When bytesPending returns 0, it means that all the data has been transferred from the write buffer to the network, and it is safe to do things like remove event handlers, null out socket references, start the next upload in a queue, etc.

`read onlyconnected:Bool`

Indicates whether this Socket object is currently connected. A call to this property returns a value of true if the socket is currently connected, or false otherwise.

`endian:Endian`

Indicates the byte order for the data. Possible values are constants from the openfl.utils.Endian class, Endian.BIG_ENDIAN or Endian.LITTLE_ENDIAN.

`read onlylocalAddress:String`

Available on AIR, Android, HashLink, Linux, Neko, Windows, iOS, macOS

The IP address this socket is bound to on the local machine.

`read onlylocalPort:Int`

Available on AIR, Android, HashLink, Linux, Neko, Windows, iOS, macOS

The port this socket is bound to on the local machine.

`objectEncoding:ObjectEncoding`

Controls the version of AMF used when writing or reading an object.

`read onlyremoteAddress:String`

Available on AIR, Android, HashLink, Linux, Neko, Windows, iOS, macOS

The IP address of the remote machine to which this socket is connected.

You can use this property to determine the IP address of a client socket dispatched in a ServerSocketConnectEvent by a ServerSocket object.

`read onlyremotePort:Int`

Available on AIR, Android, HashLink, Linux, Neko, Windows, iOS, macOS

The port on the remote machine to which this socket is connected.

You can use this property to determine the port number of a client socket dispatched in a ServerSocketConnectEvent by a ServerSocket object.

`timeout:Int`

Indicates the number of milliseconds to wait for a connection. If the connection doesn't succeed within the specified time, the connection fails. The default value is 20,000 (twenty seconds).

Methods

`close():Void`

Closes the socket. You cannot read or write any data after the close() method has been called. The close event is dispatched only when the server closes the connection; it is not dispatched when you call the close() method.

You can reuse the Socket object by calling the connect() method on it again.

Throws:

`IOError`	The socket could not be closed, or the socket was not open.

`connect(host:String, port:Int):Void`

Connects the socket to the specified host and port. If the connection fails immediately, either an event is dispatched or an exception is thrown: an error event is dispatched if a host was specified, and an exception is thrown if no host was specified. Otherwise, the status of the connection is reported by an event. If the socket is already connected, the existing connection is closed first.

Parameters:

`host`	The name or IP address of the host to connect to. If no host is specified, the host that is contacted is the host where the calling file resides. If you do not specify a host, use an event listener to determine whether the connection was successful.
`port`	The port number to connect to.

Throws:

`IOError`	No host was specified and the connection failed.
`SecurityError`	This error occurs in SWF content for the following reasons: Local untrusted SWF files may not communicate with the Internet. You can work around this limitation by reclassifying the file as local-with-networking or as trusted. You cannot specify a socket port higher than 65535. * In the HTML page that contains the SWF content, the `allowNetworking` parameter of the `object` and `embed` tags is set to `"none"`.

IOError

No host was specified and the connection failed.

SecurityError

This error occurs in SWF content for the following reasons: Local untrusted SWF files may not communicate with the Internet. You can work around this limitation by reclassifying the file as local-with-networking or as trusted. You cannot specify a socket port higher than 65535. * In the HTML page that contains the SWF content, the allowNetworking parameter of the object and embed tags is set to "none".

Events:

`connect`	Dispatched when a network connection has been established.
`ioError`	Dispatched if a host is specified and an input/output error occurs that causes the connection to fail.
`securityError`	Dispatched if a call to `Socket.connect()` attempts to connect either to a server that doesn't serve a socket policy file, or to a server whose policy file doesn't grant the calling host access to the specified port. For more information on policy files, see "Website controls (policy files)" in the OpenFL Developer's Guide and the Flash Player Developer Center Topic: <a href="http://www.adobe.com/go/devnet_security_en" scope="external">Security.

`flush():Void`

Flushes any accumulated data in the socket's output buffer. On some operating systems, flush() is called automatically between execution frames, but on other operating systems, such as Windows, the data is never sent unless you call flush() explicitly. To ensure your application behaves reliably across all operating systems, it is a good practice to call the flush() method after writing each message (or related group of data) to the socket.

Throws:

`IOError`	An I/O error occurred on the socket, or the socket is not open.

`readMultiByte(length:Int, charSet:String):String`

Reads a multibyte string from the byte stream, using the specified character set.

Parameters:

`length`	The number of bytes from the byte stream to read.
`charSet`	The string denoting the character set to use to interpret the bytes. Possible character set strings include `"shift_jis"`, `"CN-GB"`, and `"iso-8859-1"`. For a complete list, see <a href="../../charset-codes.html">Supported Character Sets. Note: If the value for the `charSet` parameter is not recognized by the current system, then the application uses the system's default code page as the character set. For example, a value for the `charSet` parameter, as in `myTest.readMultiByte(22, "iso-8859-01")` that uses `01` instead of `1` might work on your development machine, but not on another machine. On the other machine, the application will use the system's default code page.

Defined by EventDispatcher

`@:value({ useWeakReference : false, priority : 0, useCapture : false })addEventListener<T>(type:EventType<T>, listener:T ‑> Void, useCapture:Bool = false, priority:Int = 0, useWeakReference:Bool = false):Void`

Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event. You can register event listeners on all nodes in the display list for a specific type of event, phase, and priority.

After you successfully register an event listener, you cannot change its priority through additional calls to addEventListener(). To change a listener's priority, you must first call removeListener(). Then you can register the listener again with the new priority level.

Keep in mind that after the listener is registered, subsequent calls to addEventListener() with a different type or useCapture value result in the creation of a separate listener registration. For example, if you first register a listener with useCapture set to true, it listens only during the capture phase. If you call addEventListener() again using the same listener object, but with useCapture set to false, you have two separate listeners: one that listens during the capture phase and another that listens during the target and bubbling phases.

You cannot register an event listener for only the target phase or the bubbling phase. Those phases are coupled during registration because bubbling applies only to the ancestors of the target node.

If you no longer need an event listener, remove it by calling removeEventListener(), or memory problems could result. Event listeners are not automatically removed from memory because the garbage collector does not remove the listener as long as the dispatching object exists(unless the useWeakReference parameter is set to true).

Copying an EventDispatcher instance does not copy the event listeners attached to it.(If your newly created node needs an event listener, you must attach the listener after creating the node.) However, if you move an EventDispatcher instance, the event listeners attached to it move along with it.

If the event listener is being registered on a node while an event is being processed on this node, the event listener is not triggered during the current phase but can be triggered during a later phase in the event flow, such as the bubbling phase.

If an event listener is removed from a node while an event is being processed on the node, it is still triggered by the current actions. After it is removed, the event listener is never invoked again(unless registered again for future processing).

Parameters:

`type`	The type of event.
`useCapture`	Determines whether the listener works in the capture phase or the target and bubbling phases. If `useCapture` is set to `true`, the listener processes the event only during the capture phase and not in the target or bubbling phase. If `useCapture` is `false`, the listener processes the event only during the target or bubbling phase. To listen for the event in all three phases, call `addEventListener` twice, once with `useCapture` set to `true`, then again with `useCapture` set to `false`.
`priority`	The priority level of the event listener. The priority is designated by a signed 32-bit integer. The higher the number, the higher the priority. All listeners with priority n are processed before listeners of priority n-1. If two or more listeners share the same priority, they are processed in the order in which they were added. The default priority is 0.
`useWeakReference`	Determines whether the reference to the listener is strong or weak. A strong reference(the default) prevents your listener from being garbage-collected. A weak reference does not. Class-level member functions are not subject to garbage collection, so you can set `useWeakReference` to `true` for class-level member functions without subjecting them to garbage collection. If you set `useWeakReference` to `true` for a listener that is a nested inner function, the function will be garbage-collected and no longer persistent. If you create references to the inner function (save it in another variable) then it is not garbage-collected and stays persistent. Weak references are supported on some OpenFL targets only, including html5, cpp, and flash/air. On other targets, this parameter is ignored, and the reference will be strong instead.

Throws:

`ArgumentError`	The `listener` specified is not a function.

`dispatchEvent(event:Event):Bool`

Dispatches an event into the event flow. The event target is the EventDispatcher object upon which the dispatchEvent() method is called.

Parameters:

`event`	The Event object that is dispatched into the event flow. If the event is being redispatched, a clone of the event is created automatically. After an event is dispatched, its `target` property cannot be changed, so you must create a new copy of the event for redispatching to work.

Returns:

A value of true if the event was successfully dispatched. A value of false indicates failure or that preventDefault() was called on the event.

Throws:

`Error`	The event dispatch recursion limit has been reached.

`hasEventListener(type:String):Bool`

Checks whether the EventDispatcher object has any listeners registered for a specific type of event. This allows you to determine where an EventDispatcher object has altered handling of an event type in the event flow hierarchy. To determine whether a specific event type actually triggers an event listener, use willTrigger().

The difference between hasEventListener() and willTrigger() is that hasEventListener() examines only the object to which it belongs, whereas willTrigger() examines the entire event flow for the event specified by the type parameter.

When hasEventListener() is called from a LoaderInfo object, only the listeners that the caller can access are considered.

Parameters:

`type`	The type of event.

Returns:

A value of true if a listener of the specified type is registered; false otherwise.

`@:value({ useCapture : false })removeEventListener<T>(type:EventType<T>, listener:T ‑> Void, useCapture:Bool = false):Void`

Removes a listener from the EventDispatcher object. If there is no matching listener registered with the EventDispatcher object, a call to this method has no effect.

Parameters:

`type`	The type of event.
`useCapture`	Specifies whether the listener was registered for the capture phase or the target and bubbling phases. If the listener was registered for both the capture phase and the target and bubbling phases, two calls to `removeEventListener()` are required to remove both, one call with `useCapture()` set to `true`, and another call with `useCapture()` set to `false`.

`toString():String`

`willTrigger(type:String):Bool`

Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. This method returns true if an event listener is triggered during any phase of the event flow when an event of the specified type is dispatched to this EventDispatcher object or any of its descendants.

The difference between the hasEventListener() and the willTrigger() methods is that hasEventListener() examines only the object to which it belongs, whereas the willTrigger() method examines the entire event flow for the event specified by the type parameter.

When willTrigger() is called from a LoaderInfo object, only the listeners that the caller can access are considered.

Parameters:

`type`	The type of event.

Returns:

A value of true if a listener of the specified type will be triggered; false otherwise.
