GenericArrayData (Flink : Table : Common 1.12.7 API)

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

All Implemented Interfaces:

ArrayData
```
@PublicEvolving
public final class GenericArrayData
extends Object
implements ArrayData
```
An internal data structure representing data of ArrayType.
GenericArrayData is a generic implementation of ArrayData which wraps regular Java arrays.
Note: All elements of this data structure must be internal data structures and must be of the same type. See RowData for more information about internal data structures.
For non-primitive arrays, elements can contain null for representing nullability.

- Constructor Detail
  - GenericArrayData
```
public GenericArrayData(Object[] array)
```
    Creates an instance of GenericArrayData using the given Java array.
    Note: All elements of the array must be internal data structures.

```
public GenericArrayData(boolean[] primitiveArray)
```
- Method Detail
  - isPrimitiveArray
```
public boolean isPrimitiveArray()
```
    Returns true if this is a primitive array.
    A primitive array is an array whose elements are of primitive type.
  - toObjectArray
```
public Object[] toObjectArray()
```
    Converts this GenericArrayData into an array of Java Object.
    The method will convert a primitive array into an object array. But it will not convert internal data structures into external data structures (e.g. StringData to String).
