@PublicEvolving public final class GenericArrayData extends Object implements ArrayData
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.

GenericArrayData using the given Java array.
Note: All elements of the array must be internal data structures.

public boolean isPrimitiveArray()
A primitive array is an array whose elements are of primitive type.
public Object[] toObjectArray()
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).
