  • Method Details

    • extract

      List<BandData> extract(ExtractionContext context)
      Method should presents controller logic for data extraction and band tree traversal logic
      Parameters:
      context - contains band, parent band data and params
      Returns:
      list of loaded and wrapped for formatting data

    • extractData

      default List<Map<String,Object>> extractData(ExtractionContext context)

      Method may presents specific logic for for data extraction without traverse

      ex: data extraction for root band io.jmix.reports.yarg.reporting.DataExtractorImpl#extractData
      Parameters:
      context - - should contains band, parent band data and params
      Returns:
      list of loaded data
