Hi, Dan.
Thank you for the quick feedback.
I have one follow-up question:
IMHO, the XMLStreamWriter is a simple way to produce XML documents by
writing xml artifacts instead of string concation. For SDO, we already have
XMLHelper.save(). What's the add-on value to go through the XMLStreamWriter
layer? Can something take advantage of the result XMLStreamWriter?
Thanks,
Raymond

Raymond,
1) What's the use case to save a XMLDocument or DataObject to the
XMLStreamWriter? If there's no such requirement, we can get rid of them.
Well, part of the work we are doing in Celtix is to allow the
"databinding"
layer to write directly toward a XMLStreamWriter. I was hoping to use
those
methods since that is ideal.
2) With the createStreamReader() method, we can easily pipe the reader to
writer with a utility (Axiom has one). Here's the implementation in my
latest patch.
XMLStreamReader reader = createXMLStreamReader(document);
new XMLStreamSerializer().serialize(reader, writer); //
XMLStreamSerializer is the utility to pull events from the reader and
dump
them into the writer
What is the performance impact of doing that? I'm OK with doing
something
like that (and maybe even making the mentioned save() and saveObject()
methods do that) if there isn't a major performance issue with doing that.
Basically, the goal is to get the objects written out to a stream as
quickly
as possible. If "reading events from one stream and pumping them to the
output stream" isn't too bad, I'm OK with it. But if there is a
performance
impact of doing that, then I would suggest leaving the ability to write
directly to the XMLStreamWriter.
Thanks!
