@PublicEvolving public interface ArrayData
Base interface of an internal data structure representing data ofArrayType
.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.Use
GenericArrayData
to construct instances of this interface from regular Java arrays.
