Copy exact structure, data of textflow to its derieved class

Question

Hi All,
I am writing a class inherited the TextFlow ( public class
myclass extends TextFlow {} )
Now in my new class, i want it able to read textFlow from a
xml format file. So we could have a tempoary this way:
After file reading completion event, we could have:
tempFlow = TextFilter.importToFlow(e.target.data,
TextFilter.TEXT_LAYOUT_FORMAT);
Then now i want my class owns this structure and data. (this
= tempFlow)
of course, we can assign this = tempFlow.
Do you know how to do this exact copy?
Thank you for your answer,
Best,

Hi,
TextFlow not being marked final is a bug. Sorry about that.
The other classes are marked final and this is an omission.
That said moving elements from one FlowElement to another can
be accomplised fairly simply.
In order to an "exact" copy you'll want to copy the elements.
for (var idx:int = 0; idx < tempFlow.numChildren; idx++)
var elem:FlowElement = tempFlow.getChildAt(idx);
this.addChild(elem.deepCopy());
To just move the elements this will work.
while (tempFlow.numChildren)
this.addChild(tempFlow.getChildAt(0));
Note that's a recent change that addChild doesn't throw if
the parameter already has a parent. The latest code removes the
parameter from its existing parent.
