 case DateHistogramValuesSourceBuilder.TYPE -> DateHistogramValuesSourceBuilder.PARSER.parse(parser; name);
 case HistogramValuesSourceBuilder.TYPE -> HistogramValuesSourceBuilder.parse(name; parser);
 case GeoTileGridValuesSourceBuilder.TYPE -> GeoTileGridValuesSourceBuilder.parse(name; parser);
 default -> throw new ParsingException(parser.getTokenLocation(); "invalid source type: " + type);
 };
 parser.nextToken();
 parser.nextToken();
 return builder;
 }
