Class NestedRow

java.lang.Object

org.apache.paimon.data.BinarySection

org.apache.paimon.data.NestedRow

All Implemented Interfaces:

Serializable, DataGetters, DataSetters, InternalRow

public final class NestedRow
extends BinarySection
implements InternalRow, DataSetters

Its memory storage structure is exactly the same with BinaryRow. The only different is that, as NestedRow is used to store row value in the variable-length part of BinaryRow, every field (including both fixed-length part and variable-length part) of NestedRow has a possibility to cross the boundary of a segment, while the fixed-length part of BinaryRow must fit into its first memory segment.

Constructor Detail

NestedRow

public NestedRow(int arity)

Method Detail

getFieldCount

public int getFieldCount()

Description copied from interface: InternalRow

Returns the number of fields in this row.

The number does not include RowKind. It is kept separately.

Specified by:

getFieldCount in interface InternalRow

getRowKind

public RowKind getRowKind()

Description copied from interface: InternalRow

Returns the kind of change that this row describes in a changelog.

Specified by:

getRowKind in interface InternalRow

See Also:

RowKind

setRowKind

public void setRowKind(RowKind kind)

Description copied from interface: InternalRow

Sets the kind of change that this row describes in a changelog.

Specified by:

setRowKind in interface InternalRow

See Also:

RowKind

setNullAt

public void setNullAt(int i)

See BinaryRow.setNullAt(int).

Specified by:

setNullAt in interface DataSetters

setInt

public void setInt(int pos,
                   int value)

Specified by:

setInt in interface DataSetters

setLong

public void setLong(int pos,
                    long value)

Specified by:

setLong in interface DataSetters

setDouble

public void setDouble(int pos,
                      double value)

Specified by:

setDouble in interface DataSetters

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.

Specified by:

setTimestamp in interface DataSetters

setBoolean

public void setBoolean(int pos,
                       boolean value)

Specified by:

                     short value)

Specified by:
