Method Detail

initialize

public void initialize(Mod11Check constraintAnnotation)

Description copied from interface: ConstraintValidator

Initializes the validator in preparation for ConstraintValidator.isValid(Object, ConstraintValidatorContext) calls. The constraint annotation for a given constraint declaration is passed.

This method is guaranteed to be called before any use of this instance for validation.

The default implementation is a no-op.

Specified by:

initialize in interface ConstraintValidator<Mod11Check,CharSequence>

Parameters:

constraintAnnotation - annotation instance for a given constraint declaration

initialize

public void initialize(int startIndex,
                       int endIndex,
                       int checkDigitIndex,
                       boolean ignoreNonDigitCharacters,
                       int threshold,
                       char treatCheck10As,
                       char treatCheck11As,
                       Mod11Check.ProcessingDirection direction)

isCheckDigitValid

public boolean isCheckDigitValid(List<Integer> digits,
                                 char checkDigit)

Validate check digit using Mod11 checksum

Specified by:

isCheckDigitValid in class ModCheckBase

Parameters:

digits - The digits over which to calculate the checksum

checkDigit - the check digit

Returns:

true if the mod11 result matches the check digit, false otherwise
