- All Implemented Interfaces:
- org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler
- public class GapFeaturedGrammarFileHandler
- extends HeadFeaturedGrammarFileHandler
An GapFeaturedGrammarFileHandler reads grammars whose constituents are
HeadFeaturedConstituents.
The main difference from the HeadFeaturedGrammarFileHandler is that
we need to properly parse embedded constituents as the value of
the GAP feature.

characters
public void characters(char[] buf,
int offset,
int len)
throws org.xml.sax.SAXException
- Description copied from class:
GrammarFileHandler
- Called by the SAX parsing engine when characters are read outside
of any element tag. This can be called multiple times, such as
when the text spans multiple lines (depends on whitespace treatment,
whether the parser is validating, etc.). So the safe thing to do is
just hold onto the text for later use when an end-element tag is
reached (assuming we don't care about the actual form of the
original text, but just its content, which is the case for us).
We could be more careful, saving the text in states where we're
expecting text and otherwise indicating a state-specific error,
but frankly I don't care that much.
