Hi,
I'm a newbie with Lucene and I started some testing with Lucene 2.2.0.
I developed my own Analyser and my own Filter based on examples found here,
that is:
public class DiacriticAnalyser extends GermanAnalyzer {
....
@Override
public TokenStream tokenStream(String fieldName, Reader reader) {
TokenStream result = super.tokenStream(fieldName, reader);
result = new ISOLatin1DiacriticFilter(result);
return result;
}
}
public class ISOLatin1DiacriticFilter extends TokenFilter {
...
@Override
public final Token next() throws java.io.IOException {
final Token t = input.next();
if (t != null)
t.setTermText(removeDiacritics(t.termText()));
return t;
}
}
What i don't understand is: isn't the call to input.next() endless
recursive, i mean the TokenStream class is abstract and the TokenFilter
class doesn't implement next()? And who calls next(), i just call the
constructor of ISOLatin1DiacriticFilter class.
regards,
--
