GenericRowData (Flink : Table : Common 1.14.6 API)

java.lang.Object
- org.apache.flink.table.data.GenericRowData

所有已实现的接口:

RowData
```
@PublicEvolving
public final class GenericRowData
extends Object
implements RowData
```
An internal data structure representing data of RowType and other (possibly nested) structured types such as StructuredType.
GenericRowData is a generic implementation of RowData which is backed by an array of Java Object. A GenericRowData can have an arbitrary number of fields of different types. The fields in a row can be accessed by position (0-based) using either the generic getField(int) or type-specific getters (such as getInt(int)). A field can be updated by the generic setField(int, Object).
Note: All fields of this data structure must be internal data structures. See RowData for more information about internal data structures.
The fields in GenericRowData can be null for representing nullability.

```
public GenericRowData(org.apache.flink.types.RowKind kind,
                      int arity)
```
    Creates an instance of GenericRowData with given kind and number of fields.
    Initially, all fields are set to null.
    Note: All fields of the row must be internal data structures.
    
    参数:
    
    kind - kind of change that this row describes in a changelog
    
    arity - number of fields
  - GenericRowData
```
public GenericRowData(int arity)
```
    Creates an instance of GenericRowData with given number of fields.
    Initially, all fields are set to null. By default, the row describes a RowKind.INSERT in a changelog.
