Working with byte arrays
bytes.position = 0;//reset position to beginning
bytes.compress(CompressionAlgorithm.DEFLATE);// compress ByteArray
outFile("order", bytes);
myLabel.text = "Wrote order file to desktop!";
// for Flex: } // end of init()function outFile(fileName:String, data:ByteArray):void {
var outFile:File = File.desktopDirectory; // dest folder is desktop
outFile = outFile.resolvePath(fileName); // name of file to write
var outStream:FileStream = new FileStream();
// open output file stream in WRITE mode
outStream.open(outFile, FileMode.WRITE);
// write out the file
outStream.writeBytes(data, 0, data.length);
// close it
outStream.close();

The readObject() method reads an object in serialized AMF from a ByteArray and stores it in an object of the
specified type. The following example reads the order file from the desktop into a ByteArray (inBytes),
uncompresses it, and calls readObject() to store it in the XML object orderXML. The example uses a for each()
loop construct to add each node to a text area for display. The example also displays the value of the objectEncoding
property along with a header for the contents of the order file.
