  • Method Details

    • firstRowOffset

      @FinalDefault default long firstRowOffset()
      Specified by:
      firstRowOffset in interface Page<ATTR extends Any>
      Returns:
      the first row of this page, after applying the PagingChunkSource.mask(), which refers to the first row of this page.

      void invalidate()
      Invalidate the region -- any further reads that cannot be completed consistently and correctly will fail.
