public class ImplISBN13
extends ImplEAN13

Implementation of ISBN-13 (International Standard Book Number). To generate instances, please use one of the newInstance static methods in the Barcode class.

ISBN-13 barcodes are based on the GTIN (Global Trade Item Number) system and use the EAN-13 barcode symbology (also known as GTIN-13). ISBN-13 is primarily used for books and other publications, ensuring accurate tracking and identification within the global trade system.

An ISBN-13 number consists of the following components:

• A prefix of "978" or "979",
• A group identifier,
• A publisher code,
• An item number, and
• A single check digit at the end.

The components are separated by hyphens, for example: 978-1-2345-6789-7.

Note: The human readable ISBN-13 number is printed below the barcode without hyphens and above the barcode with hyphens. The latter instance is drawn outside the barcode's bounding box, which may require additional space and a downward shift of the Y-position.

Method Details

setContent

public void setContent(String content,
 boolean autoComplete,
 boolean appendOptionalChecksum)
                throws BarcodeException

Sets the ISBN-13 number to be encoded in the barcode.

The input must conform to the ISBN-13 structure, consisting of only numeric characters and hyphens ('-'). The input must include a prefix, group, publisher, and item number. For example:

    978-1-2345-6789-7

If the provided ISBN-13 number contains a check digit (at the end), the method validates it according to ISBN-13 rules.

If the provided ISBN-13 number does not contain a check digit and the autoComplete flag is set to true, the method calculates and appends the correct check digit; otherwise, a BarcodeException is thrown.

Overrides:

setContent in class ImplEAN13

Parameters:

content - the ISBN-13 number to be encoded

autoComplete - whether to automatically calculate the check digit if it is missing

appendOptionalChecksum - has no function, as ISBN-13 uses a fixed check digit which is not optional

Throws:

BarcodeException - if the content is empty, does not conform to the proper ISBN-13 format, contains an invalid check digit, or if autoComplete is false and the content is missing a check digit.
