  • Method Details

    • getInstance

      public static CheckDigit getInstance()
      Gets the singleton instance of this validator.
      Returns:
      A singleton instance of the class.

    • weightedValue

      protected int weightedValue(int charValue, int leftPos, int rightPos) throws CheckDigitException
      Calculates the weighted value of a character in the code at a specified position.

      For VATID digits are weighted by their position from left to right.

      Specified by:
      weightedValue in class ModulusCheckDigit
      Parameters:
      charValue - The numeric value of the character.
      leftPos - The position of the character in the code, counting from left to right
      rightPos - The positionof the character in the code, counting from right to left
      Returns:
      The weighted value of the character.
      Throws:
      CheckDigitException - if an error occurs calculating the weighted value

    • calculate

      public String calculate(String code) throws CheckDigitException
      Calculate a modulus Check Digit for a code which does not yet have one.
      Specified by:
      calculate in interface CheckDigit
      Overrides:
      calculate in class ModulusCheckDigit
      Parameters:
      code - The code for which to calculate the Check Digit; the check digit should not be included
      Returns:
      The calculated Check Digit
      Throws:
      CheckDigitException - if an error occurs calculating the check digit

    • calculateModulus

      protected int calculateModulus(String code, boolean includesCheckDigit) throws CheckDigitException
      Calculate the modulus for a code.

      Override to multiply the total by 10.

      Overrides:
      calculateModulus in class ModulusCheckDigit
      Parameters:
      code - The code to calculate the modulus for.
      includesCheckDigit - Whether the code includes the Check Digit or not.
      Returns:
      The modulus value
      Throws:
      CheckDigitException - if an error occurs calculating the modulus for the specified code

    • isValid

      public boolean isValid(String code)
      Validate a modulus check digit for a code.
      Specified by:
      isValid in interface CheckDigit
      Overrides:
      isValid in class ModulusCheckDigit
      Parameters:
      code - The code to validate
      Returns:
      true if the check digit is valid, otherwise false

    • toCheckDigit

      protected String toCheckDigit(int charValue) throws CheckDigitException
      Convert an integer value to a check digit.

      Note: this implementation only handles single-digit numeric values For non-numeric characters, override this method to provide integer-->character conversion.

      Override to handle charValue 10.

      Overrides:
      toCheckDigit in class ModulusCheckDigit
      Parameters:
      charValue - The integer value of the character
      Returns:
      The converted character
      Throws:
      CheckDigitException - if integer character value doesn't represent a numeric character
