URLStream

Package | flash.net
Class | public class URLStream
Inheritance | URLStream EventDispatcher Object
Implements | IDataInput

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

The URLStream class provides low-level access to downloading URLs. Data is made available to ActionScript immediately as it is downloaded, instead of waiting until the entire file is complete as with URLLoader. The URLStream class also lets you close a stream before it finishes downloading. The contents of the downloaded file are made available as raw binary data.

The read operations in URLStream are nonblocking. This means that you must use the `bytesAvailable` property to determine whether sufficient data is available before reading it. An `EOFError` exception is thrown if insufficient data is available.

All binary data is encoded by default in big-endian format, with the most significant byte first.

The security rules that apply to URL downloading with the URLStream class are identical to the rules applied to URLLoader objects. Policy files may be downloaded as needed. Local file security rules are enforced, and security warnings are raised as needed.

Property Detail

bytesAvailable | property

`bytesAvailable:uint` [read-only]

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

Returns the number of bytes of data available for reading in the input buffer. Your code must call the `bytesAvailable` property to ensure that sufficient data is available before you try to read it with one of the `read` methods.

Implementation
`public function get bytesAvailable():uint`

connected | property |

`connected:Boolean` [read-only]

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

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

Implementation
`public function get connected():Boolean`

endian | property |

`endian:String` [read-write]

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

Indicates the byte order for the data; possible values are `BIG_ENDIAN` or `LITTLE_ENDIAN`.

The default value is `Endian.BIG_ENDIAN`.

Implementation
`public function get endian():String`
`public function set endian(value:String):void`

See also

flash.utils.Endian

objectEncoding | property |

`objectEncoding:uint` [read-write]

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

Controls the version of Action Message Format (AMF) used when writing or reading an object.

Implementation
`public function get objectEncoding():uint`
`public function set objectEncoding(value:uint):void`

ObjectEncoding class
Method Detail

close | () | method

`public function close():void`

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

Immediately closes the stream and cancels the download operation. No data can be read from the stream after the `close()` method is called.

Throws

| `IOError` — The stream could not be closed, or the stream was not open.

load | () | method |

`public function load(request:URLRequest):void`

Language Version : | ActionScript 3.0

Player Version : | Flash Player 9

Begins downloading the URL specified in the `request` parameter.

Note: If a file being loaded contains non-ASCII characters (as found in many non-English languages), it is recommended that you save the file with UTF-8 or UTF-16 encoding, as opposed to a non-Unicode format like ASCII.

If the loading operation fails immediately, an IOError or SecurityError (including the local file security error) exception is thrown describing the failure. Otherwise, an `open` event is dispatched if the URL download starts downloading successfully, or an error event is dispatched if an error occurs.

By default, the calling SWF file and the URL you load must be in exactly the same domain. For example, a SWF file at www.adobe.com can load data only from sources that are also at www.adobe.com. To load data from a different domain, place a URL policy file on the server hosting the data.

You can prevent a SWF file from using this method by setting the `allowNetworking` parameter of the the `object` and `embed` tags in the HTML page that contains the SWF content.

For more information related to security, see the following:

- The security chapter in the Programming ActionScript 3.0 book and the latest comments on LiveDocs
- The Flash Player Developer Center Topic: Security

Parameters

| `request:URLRequest` — A URLRequest object specifying the URL to download. If the value of this parameter or the `URLRequest.url` property of the URLRequest object passed are `null`, Flash Player throws a null pointer error.

Events

| `complete:`Event`` — Dispatched after data has loaded successfully.
| `httpStatus:`HTTPStatusEvent`` — If access is by HTTP, and the current Flash Player environment supports obtaining status codes, you may receive these events in addition to any `complete` or `error` event.
| `ioError:`IOErrorEvent`` — The load operation could not be completed.
| `open:`Event`` — Dispatched when a load operation starts.
| `securityError:`SecurityErrorEvent`` — A load operation attempted to retrieve data from a server outside the caller's security sandbox. This may be worked around using a policy file on the server.

Throws

| `ArgumentError` — `URLRequest.requestHeader` objects may not contain certain prohibited HTTP request headers. For more information, see the URLRequestHeader class description.
| `MemoryError` — This error can occur for the following reasons: Flash Player cannot convert the `URLRequest.data` parameter from UTF8 to MBCS. This error is applicable if the URLRequest object passed to `load()` is set to perform a `GET` operation and if `System.useCodePage` is set to `true`. Flash Player cannot allocate memory for the `POST` data. This error is applicable if the URLRequest object passed to load is set to perform a `POST` operation.
| `SecurityError` — Local untrusted SWF files may not communicate with the Internet. This may be worked around by reclassifying this SWF file as local-with-networking or trusted.

Returns

| `Boolean` — `True` is returned if the byte is nonzero, `false` otherwise.

Throws

| `EOFError` — There is insufficient data available to read. If a local SWF file triggers a security warning, Flash Player prevents the URLStream data from being available to ActionScript. When this happens, the `bytesAvailable` property returns 0 even if data has been received, and any of the read methods throws an EOFError exception.
| `IOError` — An I/O error occurred on the stream, or the stream is not open.

For a complete list, see Supported Character Sets. Note: If the value for the `charSet` parameter is not recognized by the current system, then Flash Player 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, Flash Player will use the system's default code page.
