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.

Nested and Inner Type Summary

Modifier and Type	Class and Description
public static @interface	LuhnCheck.List Defines several `@LuhnCheck` annotations on the same element.

Method Summary

Modifier and Type	Method and Description
public int	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`. checkDigitIndex()
public int	Returns: the end index (inclusive) for calculating the checksum. If not specified the whole value is considered. endIndex()
public Class<?>[]	groups()
public boolean	Returns: Whether non-digit characters in the validated input should be ignored (`true`) or result in a validation error (`false`). ignoreNonDigitCharacters()
public String	message()
public Class<? extends Payload>[]	payload()
public int	Returns: the start index (inclusive) for calculating the checksum. If not specified 0 is assumed. startIndex()

checkDigitIndex	back to summary
public int checkDigitIndex() Returns:int 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`.

endIndex	back to summary
public int endIndex() Returns:int the end index (inclusive) for calculating the checksum. If not specified the whole value is considered.

groups	back to summary
public Class<?>[] groups()

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

message	back to summary
public String message()

payload	back to summary
public Class<? extends Payload>[] payload()

startIndex	back to summary
public int startIndex() Returns:int the start index (inclusive) for calculating the checksum. If not specified 0 is assumed.
