NestedRowData (Flink : Table : Common 1.12.5 API)

java.lang.Object
- org.apache.flink.table.data.binary.BinarySection
- - org.apache.flink.table.data.binary.NestedRowData

所有已实现的接口:

BinaryFormat, TypedSetters, RowData
```
@Internal
public final class NestedRowData
extends BinarySection
implements RowData, TypedSetters
```
Its memory storage structure is exactly the same with BinaryRowData. The only different is that, as NestedRowData is used to store row value in the variable-length part of BinaryRowData, every field (including both fixed-length part and variable-length part) of NestedRowData has a possibility to cross the boundary of a segment, while the fixed-length part of BinaryRowData must fit into its first memory segment.
