Method Details

getInstance

public static CheckDigit getInstance()

Gets the singleton instance of this validator.

Returns:

A singleton instance of the class.

calculateModulus

protected int calculateModulus(String code,
 boolean includesCheckDigit)
                        throws CheckDigitException

Calculate the modulus for a code.

Override to count ciphers to and check the criteria:

• The first 10 digits of the identification number must contain exactly one duplicate or triplicate digit.
• Are there three identical digits in positions 1 to 10, these identical digits must never be directly next to each other.

Overrides:

calculateModulus in class IsoIec7064HybridSystem

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
