Interface ParseListener

All Known Implementing Classes:

DefaultParseListener

public interface ParseListener

The parser uses a ParseListener to report on its progress.

There's no particularly rigerous definition for the various levels.

I suppose it would be a little cleaner to make the message levels an enumeration, but I didn't think it was worth the extra clutter.
