Annotation Type LuhnCheck


Luhn algorithm check constraint.

Allows to validate that a series of digits pass the Luhn Modulo 10 checksum algorithm. The Luhn Mod10 is calculated by summing up the digits, with every odd digit (from right to left) value multiplied by 2, if the value is greater than 9 the the result digits a summed before the total summing.

The supported type is CharSequence. null is considered valid.

      Default:
      {}
    • payload

      Class<? extends Payload>[] payload
      Default:
      {}
    • startIndex

      int startIndex
      Returns:
      the start index (inclusive) for calculating the checksum. If not specified 0 is assumed.
      Default:
      0
    • endIndex

      int endIndex
      Returns:
      the end index (inclusive) for calculating the checksum. If not specified the whole value is considered.
      Default:
      2147483647
    • checkDigitIndex

      int checkDigitIndex
      Returns:
      The index of the check digit in the input. Per default it is assumed that the check digit is the last digit of the specified range. If set, the digit at the specified index is used. If set the following must hold true: checkDigitIndex > 0 && (checkDigitIndex < startIndex || checkDigitIndex >= endIndex.
      Default:
      -1
    • ignoreNonDigitCharacters

      boolean ignoreNonDigitCharacters
      Returns:
      Whether non-digit characters in the validated input should be ignored (true) or result in a validation error (false).
      Default:
      true
