feat(iso): add MessageErrorIndicator for DE-018 wire encoding#684
Merged
Conversation
Introduces MessageErrorIndicator in org.jpos.iso for structured encoding/decoding of the DE-018 Message Error Indicator field. - Inner enum ErrorCode: ISO 8583:2023 Table D.15 error codes 0001-0013 - Inner enum Severity: REJECTED (00) / WARNING (01) - Inner class FieldError: one 14-byte error set with factory methods: - primitiveError() -- primitive DE errors - constructedError() -- sub-element errors in constructed DEs - compositeError() -- dataset/tag errors in composite DEs - withRawCode() -- private/national-use error codes - pack()/unpack() round-trip: byte-accurate to ISO 8583:2023 §DE-018 - Integrates with ISOMsg via ISOBinaryField(18, mei.pack()) - Full unit test suite: 15 tests covering all error types, severity, round-trips, edge cases and ISOMsg integration

Introduces
MessageErrorIndicatorinorg.jpos.isofor structured encode/decode of the ISO 8583 DE-018 (Message Error Indicator) field.API
Inner types
ErrorCode— ISO 8583:2023 Table D.15 codes 0001–0013;of(int)for private/national-use codesSeverity—REJECTED(00) /WARNING(01)FieldError— one 14-byte error set with factory methods for primitive, constructed, and composite DE errorsWire format
14 bytes per error set: N2 severity + N4 error code + N3 DE number + N2 sub-element + B1 dataset id + B2 dataset bit/tag. Up to 10 sets, up to 140 bytes total.
