how to add additional name-value pair in an existing flex object - apache-flex

Question

folks,
I have a question regarding adding additional name-value pairs to my existing object in Flex;
I have an object1 of Object Type
and I declare a new object2 = object1 plus some extra name-value pairs,
is there a way to attach new name-value pairs to an existing object?
Many thanks,

If I understand your question correctly, object2 is a reference pointer to object1; therefore, changes to object2 affect object1:
package
{
import flash.display.Sprite;
public class X extends Sprite
{
public function X()
{
var object1:Object = {a: "1", b: "2"};
var object2:Object = object1;
object2.c = 3;
trace("Object 2:");
for (var name:String in object2)
{
trace("Name: " + name + " = " + object2[name]);
}
trace("Object 1:");
for (var name:String in object1)
{
trace("Name: " + name + " = " + object1[name]);
}
}
}
}
...which outputs:
Object 2:
Name: a = 1
Name: c = 3
Name: b = 2
Object 1:
Name: a = 1
Name: c = 3
Name: b = 2
If you are asking whether an object or dynamic class may be cloned, you could use a function like this:
public function cloneObject(object:Object):Object
{
var newObject:Object = {};
for (var name:String in object)
{
newObject[name] = object[name];
}
return newObject;
}
