Performance issue's
Hi,
I am facing performance issue with application which plays with xml's
Problem is:
1. There are too many heavy xml embedded in flex modules swf.
2. After load of these module we start parsing that xml's in to VO's. (Value Object a simple as3 object)
3. We use these VO's at different part of application as and when necessary.
While, Profiling application using 'flash builder profiler' I encountered that step 2(parsing xml's and converting it to Vo's) is taking more time and responsible for many loitering of xml objects.
Solution is:
1. I want a utility which will generate a swf which will have as3 VO's converted from xml's.
2. Application will load that swf file and start using that VO's directly.
That means I wanted a readymade VO's so that my parsing time will be reduced.
Implementation?
So how can I embed as3 objects instead of xml's into swf/modules?
Or
How can I convert xml's into as3 VO's at compile time? (I am ready with compile time overhead than runtime)
Clue is:
In BlazeDS, We can convert Java objects into as3 objects.
So similarly can we convert xml's into as3 or xml's into java objects then into as3 objects?
Thanks & Regards,
Raj Shaikh

If your VOs are static you can always try to serialize them to disk in AMF
format and embed them using mimeType="application/octet-stream" similar to
what is described here[1]. This way you could easily deserialize those
objects without the conversion penalty. To easily update those files, you
could use any AMF enabled application to generate them, like BlazeDS,
AmfPHP, ColdFusion, FluorineFX, etc and then embed them at compile time.
I'm not sure but I think it would also be possible to load them at runtime
but didn't try it.

RE: Performance issue's

Hi Manish,
Please find steps I did to gain performance,
Extracting information from XML and converting it into VO is done in AIR application,
Code in AIR project:
function windowedapplication1_applicationCompleteHandler(event:FlexEvent):void
{
//XML information data. Demo xml is provided actual xml has thousands of line code.
var objectModelXML:XML = new XML(<Policy>
<policyNumber>POL123</policyNumber>
<policyName>RAJ</policyName>
<amount>Billion</amount>
<Attribute>
<Name>R1</Name>
<Fame>R2</Fame>
</Attribute>
</Policy>);
//registerClassAlias("ObjectModel", ObjectModel); //registering vo class ObjectModel in AIR app
var object:ObjectModel = convertXMLToObject(objectModelXML);
var ba:ByteArray = new ByteArray();
ba.writeObject(object);
trace(writeBinaryFile("om", ba));
}
private function convertXMLToObject(objectModel:XML):ObjectModel{
var object:ObjectModel = new ObjectModel();
for each(var value:XML in objectModel.children()){
if(value.localName() == "Attribute"){
object.attributeXML = value;
}else{
object[value.localName()] = value.text().toString();
}
}
return object;
}
public function writeBinaryFile(name : String, array : ByteArray) : String {
try {
var f : File = File.desktopDirectory.resolvePath(name);
var fs : FileStream = new FileStream();
fs.open(f, FileMode.WRITE);
fs.writeBytes(array);
fs.close();
return f.nativePath + " written.";
}
catch (err : Error) {
return err.name;
}
return "Error writing file.";
}
This air app will generate file name "om" on desktop. The file "om" has a as3 objects containing information of XML's
Code in Apllication, (embed om file into application)
[Embed(source="om", mimeType="application/octet-stream")]
private var om:Class;
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
// TODO Auto-generated method stub
registerClassAlias("ObjectModel", ObjectModel); //registering vo class ObjectModel with application
var byteArray:ByteArrayAsset = ByteArrayAsset(new om());
var object:Object = byteArray.readObject();
if(object is ObjectModel){ //If you don't register "ObjectModel" class then app will not need info successfully.
trace("true");
//read object information directly instead of extracting information from xml.
}
}
Common Library Code of VO: (This library swc containing various VO's will be shared among air and runtime app)
//For example, I am showing single demo class
public class ObjectModel
{
private var _policyName:String;
private var _policyNumber:String;
private var _amount:String;
private var _attributeXML:XML;
public function ObjectModel()
{
}
public function get policyName():String
{
return _policyName;
}
public function set policyName(value:String):void
{
_policyName = value;
}
public function get policyNumber():String
{
return _policyNumber;
}
public function set policyNumber(value:String):void
{
_policyNumber = value;
}
public function get amount():String
{
return _amount;
}
public function set amount(value:String):void
{
_amount = value;
}
public function get attributeXML():XML
{
return _attributeXML;
}
public function set attributeXML(value:XML):void
{
_attributeXML = value;
}
}

Thanks Maurice, it did worked.
Created a AIR application which will generate a VO's from XML's. (Vo class is shared in between air application and main application) Then generated VO's are dumped into hard disk by using ByteArray.
Dumped file then embedded into running application.
By using ByteArray.readObject taken binaray data.
Type casted object to VO class by using registerClassAsAlias method.
Smoothly working :)

Possible solution:
Use serialization =>
1) Built a utility that will parse the XML , convert them to VOs, serialize the VOs and save the result as a binary file, all at "build" time.
2) embed the binary file into your app.
3) Then at runtime, read the embedded file then deserialize to get back the VOs.

Solution is:
1. I want a utility which will generate a swf which will have as3 VO's converted from xml's.
2. Application will load that swf file and start using that VO's directly.
That means I wanted a readymade VO's so that my parsing time will be reduced.
Implementation?
So how can I embed as3 objects instead of xml's into swf/modules?
Or
How can I convert xml's into as3 VO's at compile time? (I am ready with compile time overhead than runtime)
Clue is:
In BlazeDS, We can convert Java objects into as3 objects.
So similarly can we convert xml's into as3 or xml's into java objects then into as3 objects?

Other people have performance issues here as well. An alternative
solution to pre-computing the VO's at compile time is to use lazy or
on-demand XML to VO conversion. There is a prototype of a LazyCollection
that does JSON to VO conversion in the FlexJS prototype. Source is in the
asjs repo.
In general, performance will benefit from doing things like conversion
on-demand. For sure if you can know it at compile-time that is usually
the best, but keep in mind that even VO's are not linked into the SWF as a
block of binary memory. Code will still run at some point in time to
either parse the AMF stream, and/or create instances of VO's and populate
them with properties. If you generate 100K objects at startup and only
use 10 of them at a time, you might still be better off with lazy
conversion at runtime.
Also, some folks even implement fancy VO's that lazily convert sub-objects
of the VO. One XML data set I saw had 50 records, but each record had the
entire transaction history of the customer, each of which had 1000's of
transactions. The initial screen just showed customer name and not the
transaction history, so there was no point in converting 50,000
transaction records just to see the list of customer names. It was later,
when you selected the actual customer to drill-down that the 1000 records
for that customer was converted.
