Validation

public enum Validation : UInt32

Optional AI validation procedures that may be applied to detect invalid inputs.

These validation procedures are applied when AI data is provided using setAIdataStr(_:), setDataStr(_:) or setScanData(_:).

Note

Some validation procedures are “locked” (always enabled and cannot be modified). All validation procedures are listed to maintain correct enum value alignment with the native library.

  • Mutually exclusive AIs (locked: always enabled)

    Declaration

    Swift

    case MutexAIs = 0

  • Mandatory associations between AIs

    Declaration

    Swift

    case RequisiteAIs = 1

  • Repeated AIs having same value (locked: always enabled)

    Declaration

    Swift

    case RepeatedAIs = 2

  • Serialisation qualifier AIs must be present with Digital Signature (locked: always enabled)

    Declaration

    Swift

    case DigSigSerialKey = 3

  • Unknown AIs not permitted as GS1 DL URI data attributes

    Declaration

    Swift

    case UnknownAInotDLattr = 4

  • Value is the number of validations

    Declaration

    Swift

    case NUMVALIDATIONS = 5
