Ugh…never mind. -keep-as3-metadata Autowired

So, I am trying to run this on a module after it’s loaded, but the [Autowired] metadata nodes don’t show up in the typeDescription. The Bindable metadata is all there, and the var I decorated is there, it just doesn’t have the Autowired metadata. Any ideas what I am messing up?

Thanks,
Ruprict

This method is very appealing, however have you seen a noticeable performance impact? It seems like it could be expensive using as3 “reflection” (parsing an xml document) every time any UIComponent in the application is added as a child to something.

[property file="something.properties"/]

Wish it were that easy in Spring proper Good job Christophe! Way to go, team!
And I love the “method-invocation” tag, by the way

Yes, I should have updated the code since that method has changed a bit since this post was published.

Here is a newer version of the autowiring code. It does not use AS3Reflect for performance reasons.

You’ll manually need to import the following:
import mx.utils.DescribeTypeCache;
import mx.utils.DescribeTypeCacheRecord;

(I’ll also update the code)

***

private function onAdded(event:Event):void {
var autowiredObject:Object = event.target;
var typeInfo:DescribeTypeCacheRecord = DescribeTypeCache.describeType(autowiredObject);

for each (var metaDataNode:XML in typeInfo.typeDescription..metadata) {
if (metaDataNode.attribute(“name”) == “Autowired”) {
var propertyNode:XML = metaDataNode.parent();
var property:String = propertyNode.@name.toString();
var objectName:String = property;
var autowireByType:Boolean = true;

for each (var arg:XML in metaDataNode.arg) {
if (arg.attribute(“value”) == “byName”) {
autowireByType = false;
}
}

if (autowireByType) {
var clazz:Class = ClassUtils.forName(propertyNode.@type.toString());
var objectNames:Array = m_applicationContext.getObjectNamesForType(clazz);
if (objectNames.length == 1) {
objectName = objectNames[0];
}
}

autowiredObject[property] = m_applicationContext.getObject(objectName);
}
}
}

I’m trying to use autowiring but with the latest Spring ActionScript 0.7.1 and the version of as3reflect included I get an array when I call accessor.getMetaData(“Autowired”) instead of a single MetaData object

Hi Herrodius, hopefully some people understood some things you said !

Keep it up!
