    I am confused here, the return value is not the parsed value, but the length that got
parsed.

> In order to parse CSV files using the new Table API that converts rows to Row objects
(that support null values), FiledParser implementations should support emptry strings setting
the parser state to ParseErrorState.EMPTY_STRING (for example FloatParser and DoubleParser
doesn't respect this constraint)
