NestedRow (Paimon : Common 0.6.0-incubating API)

java.lang.Object
- org.apache.paimon.data.BinarySection
- - org.apache.paimon.data.NestedRow

所有已实现的接口:

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.

    从接口复制的说明: 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.

    从接口复制的说明: 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.
