Method Details

getInstance

public static CheckDigit getInstance()

Gets the singleton instance of this validator.

Returns:

A singleton instance of the class.

getCheckdigitLength

protected int getCheckdigitLength()

Overrides:

getCheckdigitLength in class ModulusCheckDigit

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 map charValue to alphanumerics.

Override to handle charValues between 0 and 88.

Overrides:

toCheckDigit in class Modulus31CheckDigit

Parameters:

charValue - The integer value of the character

Returns:

The converted character

Throws:

CheckDigitException - if integer character value doesn't represent a numeric character
