  • Method Details

    • initialize

      public void initialize(Digits 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<Digits,CharSequence>
      Parameters:
      constraintAnnotation - annotation instance for a given constraint declaration

    • isValid

      public boolean isValid(CharSequence charSequence, ConstraintValidatorContext constraintValidatorContext)
      Description copied from interface: ConstraintValidator
      Implements the validation logic. The state of value must not be altered.

      This method can be accessed concurrently, thread-safety must be ensured by the implementation.

      Specified by:
      isValid in interface ConstraintValidator<Digits,CharSequence>
      Parameters:
      charSequence - object to validate
      constraintValidatorContext - context in which the constraint is evaluated
      Returns:
      false if value does not pass the constraint
