Method Detail

initialize

public void initialize(Mod10Check 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<Mod10Check,CharSequence>

Parameters:

constraintAnnotation - annotation instance for a given constraint declaration

isCheckDigitValid

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

Validate check digit using Mod10

Specified by:

isCheckDigitValid in class ModCheckBase

Parameters:

digits - The digits over which to calculate the checksum

checkDigit - the check digit

Returns:

true if the mod 10 result matches the check digit, false otherwise
