DataGetters
The precision and scale are required to determine whether the decimal value was stored in
a compact representation (see Decimal
).

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

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