Michael McCandless updated TIKA-870:
------------------------------------
Attachment: TIKA-870.patch
Patch, with the sample code plus a test case.
The test case failed at first! Ie, the returned string was over the specified
limit... I dug and discovered WriteOutContentHandler wasn't overriding/counting
ignorableWhitespace, so I added that override and now the test passes.
I think it's ready...
> Allow to use call parseToString with a additional parameter of
> MaxStringLength, so it can be changed per call

> It would be great to be able to call parseToString with an additional
> parameter of the maxStringLength, instead of having to set it on the Tika
> instance. This allows to set it per parse call. Sample code:
> {code}
> public String parseToString(InputStream stream, Metadata metadata, int
> maxStringLength)
> throws IOException, TikaException {
> WriteOutContentHandler handler =
> new WriteOutContentHandler(maxStringLength);
> try {
> ParseContext context = new ParseContext();
> context.set(Parser.class, parser);
> parser.parse(
> stream, new BodyContentHandler(handler), metadata, context);
> } catch (SAXException e) {
> if (!handler.isWriteLimitReached(e)) {
> // This should never happen with BodyContentHandler...
> throw new TikaException("Unexpected SAX processing failure", e);
> }
> } finally {
> stream.close();
> }
> return handler.toString();
> }
> {code}
