Java SAXParser - keep InputStream open

Question

I've a BufferedInputStream from which I want to parse XML with SAXParser but then reuse it again (eg. mark(int) & reset()). However this stream is closed in parse() method. Is it possible to somehow tell SAXParser to leave it open? The last resort is to wrap this stream with un-closeable stream.

Thank you.

How about something like:

class WontCloseBufferedInputStream extends BufferedInputStream {
  public void close () {
    // Do nothing.
  }

  public void reallyClose() {
    super.close ();
  }
}

I am interested to know why you see this as a last resort. It does exactly what you want. – OldCurmudgeon Dec 01 '11 at 14:40

Because it's ugly. IMO library shouldn't close passed in InputStream/Reader. – woky Aug 04 '13 at 14:36

You can pass InputSource object rather than InputStream object to SAXParser

sample code

SAXParser parser = // saxpaser object
        InputSource isource = new InputSource();
        InputStream istream = //your inputstream
        isource.setByteStream(istream);
        parser.parse(isource, handler);

Is the `InputSource` closed when the parser completes? If so this is unhelpful. – OldCurmudgeon Dec 01 '11 at 13:58
But then this post doesn't solve the problem neither hints the solution :o) – Theodor Keinstein Mar 28 '12 at 06:43
