som feedback (late in the game ...)
I have seen the Parent/Child stuff in CVS but never actually looked at
the changes and consequences in detail. Until now.
To me, the Parent/Child/Container/Content/whatever stuff is really of no
practical use. Over the years (four, isn't it?) I've acquired a certain
coding style, which is now suddenly subliminally altered. There was once
an interface-less vision, which is now blurred. Funny thing, when I
collective JDOM code, I never seem to treat a Document node the same as
Element node! In fact 99.99% (or close) of my processing is concerned
with either an
Element, an Attribute or a Text node. I think there isn't enough
to justify a Parent abstraction, at least not in the practical cases.
I really think these changes are going to make more harm than good,
the (long) history of the API.
As an experiment, I took the beta-10 code and applied it to an older
with beta-7 and where beta-9 worked OK. This code does some really
intricate navigation inside a rather large, validated, document.
Element#getParent() not being an Element
really blowed that piece of code away!!
As for the method names, getChildren/getChildElements, etc: this issue
is of minor
importance, considering the modern IDEs (as long as the behaviour is
For the record, I would prefer getChildElements (or even
naming standard is overused).
I think this is my point: Stick with the initial vision, follow through
consequences. You are never going to achieve the perfect API**. Skip
Two other issues, perhaps on a smaller scale:
*) Did you consider the change I proposed to XMLOutputter?
*) Why can't I *get* the current Format from XMLOutputter?
Or maybe this is the "Quest for the Holy API". We are are all going to
on a Scottish moor for believing in an ephemeral computational vision,
thus being a
threat to the IT society as a virtual impossibility ....
