   It looks like Row.getValues is often used to do a raw copy - e.g. return 
Row.withSchema(schema).attachValues(row.getValues());
   
   If you want to do a larger refactor (and intelliJ should make this easy), 
you can rename getValues() -> getRawValues(), and add a new getValues() that 
does what you want; this might make the Row methods a bit less confusing. 
Otherwise you can simply do it inline here - e.g. 
IntStream.range(row.getSize()).map(i -> 
row.get(i)).collect(Collectors.toList());

> RowCoderGenerator.encodeDelegate calls getValue for each field on a row 
> twice, one to check if it is null in scanNullFields, and one to actually get 
> the value to be encoded. 
> If getValue is expensive (for example, it has to recursively adapt a type to 
> a beam Row), this causes unneeded extra work.
> Instead we could call value.getValues to get all values once, then pass them 
> to scanNullFields and re-use them when encoding the values.
