                       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,

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.
