Hi list,
The following puzzles me:
//code in frame 1
1 var xmlData:xml;
2 trace(typeof(xmlData)); //'object' not
xml??
//mijnXml.getHetXmlObject() is a method of a custom class that is
supposed to return an xml-object
//code that loads the xml is ommitted
3 trace(typeof(mijnXml.getHetXmlObject())); //'object' not xml??
4 xmlData = mijnXml.getHetXmlObject();
//called from a button I have the following:
6 trace(typeof(mijnXml.getHetXmlObject())); //'xml'
7 trace(typeof(xmlData)); //'object' ???
My questions:
Why does flash see 'xmlData' as an object in line 2 although I
specifically type it as 'xml' in line 1?
I understand that in line 3 somehow flash has not yet determined the
type of the variable (not yet fully loaded?). Only after a while it
'sees' the correct type (line 6). Is that correct?
From Moock's EAS3 (p30) I understand that, as the type of the
original variable (returned by mijnXml.getHetXmlObject()) is an
object (line 3), xmlData holds only a _reference_ to the original
variable.
Thus, when the original variable changed to type 'xml', xmlData
should also become type 'xml'. But according to line 7 it is still an
object.
Why??
Thanks,
Willem van den Goorbergh
