| | | getChildren() usage | getChildren() usage 2003-09-30 - By Eugene Fabrikant
Back
This is a request for a sanity check:
I'm attempting to use the getChildren() method in the Element class. Upon
debugging I see that the Element is properly populated with correctly
parsed XML elements. When I call the method, the list returned is
consistently empty, regardless of the XML file I use. All documentation
that I found says that I should be able to use this method and expect a
corresponding List of first level children.
Finally I looked in the source code and found this note in the inner class
FilterList:
// Implementation Note: Directly after size() is called,
expected
// is sync'd with ContentList.modCount and count provides
// the true size of this view. Before the first call to
// size() or if the backing list is modified outside this
// FilterList, both might contain bogus values and should
// not be used without first calling size();
This does in fact correctly update the count in the FilterList
representation of the ContentList. It is hard to believe that I have to
call the size() method after every getChildren() method call. Is that in
fact the case, or am I just completely missing some step? I did not find
any examples that mentioned this awkward usage. If I'm not missing
anything how do I go about contributing a change to this, or even
suggesting one?
Thank You,
