Method Details

getInstance

public static CheckDigit getInstance()

Gets the singleton instance of this validator.

Returns:

A singleton instance of the class.

getCharacterSet

protected String getCharacterSet()

Description copied from class: IsoIec7064PureSystem

MOD 11-2 check characters are “0” to “9” plus “X” for example.

Overrides:

getCharacterSet in class IsoIecPure11System

Returns:

a String containing characters the check digit is build from. This can be IsoIecConstants.NUMERIC, IsoIecConstants.ALPHABETIC, IsoIecConstants.ALPHANUMERIC , IsoIecConstants.NUMERIC_PLUS_X, IsoIecConstants.ALPHANUMERIC_PLUS_STAR

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 IsoIec7064PureSystem

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

isValid

public boolean isValid(String code)

Specified by:

isValid in interface CheckDigit

Overrides:

isValid in class IsoIec7064PureSystem

Parameters:

code - The code to validate

Returns:

true if the check digit is valid, otherwise false
