public GeneratedRowWriter.RowWriterBuilder withExtractor(String fieldName,
                                                         Extractor extractor)
```
  - withFieldWriterFactory
```
public GeneratedRowWriter.RowWriterBuilder withFieldWriterFactory(String fieldName,
                                                                  FieldWriterFactory factory)
```
    Used to override the default FieldWriter for the given field. For example, you might use this if your source stores DateDay using java type Y but our default FieldWriter for DateDay only accept type Z even though Apache Arrow has a native setter for type Y. By proving your own FieldWriterFactory you can avoid the extra step of translating to an intermediate type.
    
    Parameters:
    
    fieldName - The name of the field who's factory you'd like to override.
    
    factory - The factory you'd like to use instead of the default.
    
    Returns:
    
    This builder.
  - build
```
public GeneratedRowWriter build()
