    • setDecimal

      public void setDecimal(int pos, DecimalData value, int precision)
      Description copied from interface: TypedSetters
      Set the decimal column value.

      Note: Precision is compact: can call TypedSetters.setNullAt(int) when decimal is null. Precision is not compact: can not call TypedSetters.setNullAt(int) when decimal is null, must call setDecimal(pos, null, precision) because we need update var-length-part.

      Specified by:
      setDecimal in interface TypedSetters

    • setTimestamp

      public void setTimestamp(int pos, TimestampData value, int precision)
      Description copied from interface: TypedSetters
      Set Timestamp value.

      Note: If precision is compact: can call TypedSetters.setNullAt(int) when TimestampData value is null. Otherwise: can not call TypedSetters.setNullAt(int) when TimestampData value is null, must call setTimestamp(pos, null, precision) because we need to update var-length-part.
