Package io.github.mrtyldr.datev.validation

Class DatevValidator

java.lang.Object
io.github.mrtyldr.datev.validation.DatevValidator
All Implemented Interfaces:
BiConsumer<Integer,List<String>>
public final class DatevValidator extends Object implements BiConsumer<Integer,List<String>>
Immutable, implementation-neutral DATEV Buchungsstapel row validator.

This class is a thin adapter: it binds the shared validation core in datev-exporter-core to the BiConsumer<Integer, List<String>> callback that both lean DatevFile factories accept, without linking this artifact to either exporter implementation.

The validator receives logical, unquoted values. CSV parsing and escaping remain the responsibility of the selected exporter.
