RFR (jaxp) 8136778: SAXParser: support stopping a parsing process (original) (raw)

Hi Joe,

The spec for stop says:

561 * This method can be called anywhere from any event method of a SAX 562 * handler. Once called, it does not terminate the parsing process 563 * immediately. Instead, it will continue finishing and returning the 564 * current event, and marking the state before it stops parsing. The 565 * parsing state is maintained after the process is stopped.

I wonder whether the step should be extended with some more testcases, calling stop() from various event methods, and not just endElement() - to validate that stop() resume() will work as expected.

Also what will happen if resume() is called before the parser has finished flushing the current event? Will that work? Or should there be some guards against that?

best regards,

Hi,

This is an enhancement to allow a SAX parsing process to be stopped and resumed. A SAX process scans through an entire document while making callbacks to its handler when defined events are met. The stop and resume methods make it easy to stop and subsequently resume the process as needed. Until now, the parsing process can only be stopped brutally by throwing an Exception.
