1.如何動態(tài)獲取Object中的屬性和值
var ct:CustomObject=newCustomObject();
var xml:XML = describeType(ct);
for each(var accessor in xml..accessor){
var name:String= accessor.@name;
var type:String= accessor.@type;
trace(ct[name]);
}
2. 對象之間的拷貝
/**
* copies a source object to a destination object

* @param destinationObject the destination object

//retrive information about the source object via XML
var sourceInfo:XML = describeType(sourceObject);
var objectProperty:XML;
var propertyName:String;

propertyName = objectProperty.@name;
if(sourceObject[objectProperty.@name] != null)

}
}
}
catch (err:*) {
