getString

public StringData getString(int pos)

Description copied from interface: ArrayData

Returns the string value at the given position.

Specified by:

getString in interface ArrayData

getDecimal

public DecimalData getDecimal(int pos,
                              int precision,
                              int scale)

Description copied from interface: ArrayData

Returns the decimal value at the given position.

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

Specified by:

getDecimal in interface ArrayData

getTimestamp

public TimestampData getTimestamp(int pos,
                                  int precision)

Description copied from interface: ArrayData

Returns the timestamp value at the given position.

The precision is required to determine whether the timestamp value was stored in a compact representation (see TimestampData).

Specified by:

getTimestamp in interface ArrayData

getRawValue

public <T> RawValueData<T> getRawValue(int pos)

Description copied from interface: ArrayData

Returns the raw value at the given position.

Specified by:

Description copied from interface: ArrayData

Returns the row value at the given position.

The number of fields is required to correctly extract the row.

Specified by:

getRow in interface ArrayData

setBoolean

public void setBoolean(int pos,
                       boolean value)

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.
