Barcode-Lib4J requires Java 11+

Package de.vwsoft.barcodelib4j.oned

Java Class «ImplPZN» – Barcode «PZN»

java.lang.Object

de.vwsoft.barcodelib4j.oned.Barcode

de.vwsoft.barcodelib4j.oned.ImplCode39

de.vwsoft.barcodelib4j.oned.ImplPZN

All Implemented Interfaces:

Cloneable

public class ImplPZN
extends ImplCode39

Implementation of PZN (the older 7-digit format). To create instances, use one of the newInstance static methods in the Barcode class.

The PZN (Pharmazentralnummer) is a German barcode standard used to identify pharmaceutical products. It consists of 6 digits for the product identifier plus a check digit.

In the barcode symbol, the hyphen (-) is included by placing it in front of the number.

The human readable text line for the PZN barcode consists of the prefix 'PZN', followed by a space, then a hyphen, and then the 6-digit product identifier, followed by the check digit at the end. For example:

    PZN -1234562

PZN is not a standalone barcode type but uses the Code 39 format to encode its data.

Method Details

setContent

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

Sets the content to be encoded in the barcode.

If the autoComplete parameter is true and the length of the content is 6, the method calculates the checksum and appends it to the content, ensuring a total length of 7. If the calculated checksum is 10, a BarcodeException is thrown because this value is invalid.

If autoComplete is false, the method validates that the content length is 7 and checks if the last digit matches the calculated checksum. If not, a BarcodeException is thrown.

Overrides:

setContent in class ImplCode39

Parameters:

content - the PZN 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 PZN uses a fixed check digit which is not optional

Throws:

BarcodeException - if the content is empty, contains invalid characters, is of incorrect length, has an invalid check digit, or if the calculated checksum is 10
