@PublicEvolving public final class GenericRowData extends Object implements RowData
RowType and other (possibly nested)
structured types such as StructuredType.
GenericRowData is a generic implementation of RowData which is backed by an
array of Java Object. A GenericRowData can have an arbitrary number of fields of
different types. The fields in a row can be accessed by position (0-based) using either the
generic getField(int) or type-specific getters (such as getInt(int)). A field
can be updated by the generic setField(int, Object).
Note: All fields of this data structure must be internal data structures. See RowData
for more information about internal data structures.
The fields in GenericRowData can be null for representing nullability.
