      public JoinedRowData()
      Creates a new JoinedRowData of kind RowKind.INSERT, but without backing rows.

      Note that it must be ensured that the backing rows are set to non-null values before accessing data from this JoinedRowData.

    • JoinedRowData

      public JoinedRowData(@Nullable RowData row1, @Nullable RowData row2)
      Creates a new JoinedRowData of kind RowKind.INSERT backed by and .

      Note that it must be ensured that the backing rows are set to non-null values before accessing data from this JoinedRowData.
