- Constructor Detail
  - JoinedRow
```
public JoinedRow()
```
    Creates a new JoinedRow 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 JoinedRow.
  - JoinedRow
```
public JoinedRow(@Nullable
                 InternalRow row1,
                 @Nullable
                 InternalRow row2)
```
    Creates a new JoinedRow of kind RowKind.INSERT backed by row1 and row2.
    Note that it must be ensured that the backing rows are set to non-null values before accessing data from this JoinedRow.
    
    Parameters:
    
    row1 - the first row
    
    row2 - the second row
  - JoinedRow
```
public JoinedRow(RowKind rowKind,
                 @Nullable
                 InternalRow row1,
                 @Nullable
                 InternalRow row2)
```
    Creates a new JoinedRow of kind RowKind.INSERT backed by row1 and row2.
    Note that it must be ensured that the backing rows are set to non-null values before accessing data from this JoinedRow.
    
    Parameters:
