所有超级接口:

TypeGetterSetters

所有已知实现类:

BinaryArray, GenericArray
```
public interface BaseArray
extends TypeGetterSetters
```
An interface for array used internally in Flink Table/SQL.
There are different implementations depending on the scenario: After serialization, it becomes the BinaryArray format. Convenient updates use the GenericArray format.

方法概要

所有方法实例方法抽象方法
限定符和类型	方法和说明
`boolean`	`isNullAt(int pos)` Because the specific row implementation such as BinaryRow uses the binary format.
`int`	`numElements()`
`void`	`setNotNullAt(int pos)`
`void`	`setNullAt(int pos)` Set null to this field.
`void`	`setNullBoolean(int pos)`
`void`	`setNullByte(int pos)`
`void`	`setNullDouble(int pos)`
`void`	`setNullFloat(int pos)`

- 方法详细资料
  - numElements
```
int numElements()
```
  - isNullAt
```
boolean isNullAt(int pos)
```
    从接口复制的说明: TypeGetterSetters
    
    Because the specific row implementation such as BinaryRow uses the binary format. We must first determine if it is null, and then make a specific get.
    
    指定者:
    
    isNullAt 在接口中 TypeGetterSetters
    
    返回:
    
    true if this field is null.
  - setNullAt
```
void setNullAt(int pos)
```
    从接口复制的说明: TypeGetterSetters
    
    Set null to this field.
    
    指定者:
    
    setNullAt 在接口中 TypeGetterSetters
  - setNotNullAt
```
void setNotNullAt(int pos)
```
