public void initialize(Mod10Check constraintAnnotation)

Overrides default jakarta.validation.ConstraintValidator.initialize.

Doc from jakarta.validation.ConstraintValidator.initialize.

Initializes the validator in preparation for 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.

Parameters
constraintAnnotation:Mod10Check

annotation instance for a given constraint declaration

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

Implements abstract org.hibernate.validator.internal.constraintvalidators.hv.ModCheckBase.isCheckDigitValid.

Validate check digit using Mod10

Parameters
digits:List<Integer>

The digits over which to calculate the checksum

checkDigit:char

the check digit

Returns:boolean

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