GenericArray (Paimon : Common 0.6.0-incubating API)

java.lang.Object
- org.apache.paimon.data.GenericArray

所有已实现的接口:

Serializable, DataGetters, InternalArray
```
@Public
public final class GenericArray
extends Object
implements InternalArray, Serializable
```
An internal data structure representing data of ArrayType.
Note: All elements of this data structure must be internal data structures and must be of the same type. See InternalRow for more information about internal data structures.
GenericArray is a generic implementation of InternalArray which wraps regular Java arrays.

从以下版本开始:

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

public GenericArray(boolean[] primitiveArray)
```
- 方法详细资料
  - 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 GenericArray 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. BinaryString to String).
  - size
```
public int size()
```
