Package de.vwsoft.barcodelib4j.oned

Java Class «ImplEAN14» – Generate EAN-14 Barcode

java.lang.Object

de.vwsoft.barcodelib4j.oned.Barcode

de.vwsoft.barcodelib4j.oned.ImplCode128

de.vwsoft.barcodelib4j.oned.ImplEAN128

de.vwsoft.barcodelib4j.oned.ImplEAN14

All Implemented Interfaces:

Cloneable

public class ImplEAN14
extends ImplEAN128

Implementation of EAN-14 (also known as GTIN-14) using GS1-128. To generate instances, please use one of the newInstance static methods in the Barcode class.

This convenience class generates a GS1-128 barcode that contains a 14-digit GTIN as the sole data element. It automatically includes the Application Identifier prefix '01' in both the barcode and the human readable text line, allowing you to specify only the GTIN number itself.

Note: Encoding the same GTIN number with this class and with the GS1-128 implementation will produce exactly the same barcode.

Method Details

setContent

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

Sets the GTIN number to be encoded in the barcode.

The number must be either 14 (with check digit) or 13 (without check digit) in length.

• If the number contains 14 digits, the 14th digit is checked to see if it is a valid check digit. If the check digit is invalid, a BarcodeException is thrown.
• If the number contains 13 digits and autoComplete is set to true, the method calculates the missing check digit and appends it to the specified number. If autoComplete is set to false, a BarcodeException is thrown.

Overrides:

setContent in class ImplEAN128

Parameters:

content - the GTIN number to be encoded in the barcode

autoComplete - whether to automatically calculate and append a check digit if it is missing

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

Throws:

BarcodeException - if the content is empty, contains non-numeric characters, is of invalid length, or has an invalid check digit
