Returns the integer value at the given position.

Specified by:

getInt in interface DataGetters

getLong

public long getLong(int pos)

Description copied from interface: DataGetters

Returns the long value at the given position.

Specified by:

getLong in interface DataGetters

getFloat

public float getFloat(int pos)

Description copied from interface: DataGetters

Returns the float value at the given position.

Specified by:

getFloat in interface DataGetters

getDouble

public double getDouble(int pos)

Description copied from interface: DataGetters

getString

public BinaryString getString(int pos)

Description copied from interface: DataGetters

Returns the string value at the given position.

Specified by:

getString in interface DataGetters

getDecimal

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

Description copied from interface: DataGetters

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 Decimal).

Specified by:

getDecimal in interface DataGetters

getTimestamp

public Timestamp getTimestamp(int pos,
                              int precision)

Description copied from interface: DataGetters

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 Timestamp).

Specified by:

getTimestamp in interface DataGetters

getBinary

public byte[] getBinary(int pos)

Description copied from interface: DataGetters

Returns the binary value at the given position.

Specified by:

getBinary in interface DataGetters

Description copied from interface: DataGetters

Returns the map value at the given position.

Specified by:

getMap in interface DataGetters

public InternalRow getRow(int pos,
                          int numFields)

Description copied from interface: DataGetters

Returns the row value at the given position.

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

Specified by:

getRow in interface DataGetters

setBoolean

public void setBoolean(int pos,
                       boolean value)

Specified by:

                    long value)

Specified by:

setLong in interface DataSetters

setFloat

public void setFloat(int pos,
                     float value)

setDecimal

public void setDecimal(int pos,
                       Decimal value,
                       int precision)

Description copied from interface: DataSetters

Set the decimal column value.

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.

Specified by:

setDecimal in interface DataSetters

setTimestamp

public void setTimestamp(int pos,
                         Timestamp value,
                         int precision)

Description copied from interface: DataSetters

Set Timestamp value.

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.
