Kristian Rosenvold updated JENA-713:
------------------------------------
Attachment: rev2.patch
testCase.patch
I have now attached am extensive testcase which covers most of FmtUtils. The
testcase can be applied before or after "rev2.patch", it passes in both cases.
As for the comment about using the StringBuilder with the output stream, that
one method reads a little weirder than most. It is still a lot more efficient
though, since there is only 1 stringbuilder in action, whereas the old version
would have numerous instances working within the different methods.
This also means that none of the "string" versions are in use inside FmtUtils
itself any more, and it might be possible to deprecate these. I could look at
that once this goes through...

> The enclosed patch improves performance for all kinds of string-serialization
> of rdf graphs. The patch improves the performance of "UpdateRequest.output"
> by approx. 30%, whcih makes remote sparql queries a fair bit faster. The
> patch will probably improve performance across the board.
