      @Nonnull public InfluxQLQueryResult query(@Nonnull InfluxQLQuery influxQLQuery)
      Description copied from interface: InfluxQLQueryApi
      Executes an InfluxQL query against the legacy endpoint.
      Specified by:
      query in interface InfluxQLQueryApi
      Parameters:
      influxQLQuery - the query
      Returns:

    • query

      @Nonnull public InfluxQLQueryResult query(@Nonnull InfluxQLQuery influxQLQuery, @Nullable InfluxQLQueryResult.Series.ValueExtractor valueExtractor)
      Description copied from interface: InfluxQLQueryApi
      Executes an InfluxQL query against the legacy endpoint. The value extractor is called for each resulting column to convert the string value returned by query into a custom type.

      Example: 

       InfluxQLQueryResult result = influxQLQueryApi.query(
             new InfluxQLQuery("SELECT FIRST(\"free\") FROM \"influxql\"", DATABASE_NAME)
                     .setPrecision(InfluxQLQuery.InfluxQLPrecision.SECONDS),
             (columnName, rawValue, resultIndex, seriesName) -> {
                 switch (columnName) {
                     case "time":
                         return Instant.ofEpochSecond(Long.parseLong(rawValue));
                     case "first":
                         return new BigDecimal(rawValue);
                     default:
                         throw new IllegalArgumentException("unexpected column " + columnName);
                 }
             }
     );
      Specified by:
      query in interface InfluxQLQueryApi
      Parameters:
      influxQLQuery - the query
      valueExtractor - a callback, to convert column values
      Returns:
      the result
