Examples of org.apache.lucene.document.Fieldable.stringValue()

org.apache.lucene.document.Fieldable.stringValue()
The value of the field as a String, or null.
For indexing, if isStored()==true, the stringValue() will be used as the stored field value unless isBinary()==true, in which case getBinaryValue() will be used. If isIndexed()==true and isTokenized()==false, this String value will be indexed as a single token. If isIndexed()==true and isTokenized()==true, then tokenStreamValue() will be used to generate indexed tokens if not null, else readerValue() will be used to generate indexed tokens if not null, else stringValue() will be used to generate tokens.

          }
          tokenStream.end();
          tokenStream.close();
        } else {
          // untokenized
          String fieldVal = field.stringValue();
          Token token = new Token(0, fieldVal.length(), "untokenized");
          token.setEmpty().append(fieldVal);
          tokens.add(token);
          fieldSetting.fieldLength++;
