public class Std2of5Barcode

extends LinearBarcode

This is a concrete implementation of the Standard 2 of 5 barcode The Standard 2 of 5 barcode requires an even number of characters. At the same time, a modulo 10 check digit can be used. The default constructor presumes that if the barcode is of an odd length, then a check digit is required. This will automaticaly be generated. If the constructor with the check digit flag is used, the check digit flag is flase and the length of the barcode is odd, then an exception will be thrown.
