de.vwsoft.barcodelib4j.oned.ImplCode128B

All Implemented Interfaces:

Cloneable

public class ImplCode128B
extends ImplCode128

Implementation of Code 128 B. To generate instances, please use one of the newInstance static methods in the Barcode class.

Code 128 B is a subset of Code 128, capable of encoding ASCII characters with values from 32 to 127, covering:

• Upper and lower case letters (A-Z, a-z)
• Digits (0-9)
• Space character
• Punctuation and special characters: !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~

In addition, Function Codes (FNC1 to FNC4) can be used within the provided input to meet specific application requirements.

Code 128 B uses an internal checksum included within the barcode symbol but not displayed in plaintext representation.

Method Details

setContent

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

Sets the content to be encoded in the barcode.

Validates the provided content to ensure that it contains only ASCII characters with values between 32 and 127, and throws a BarcodeException if it does not.

The provided content can also include Function Codes FNC1 to FNC4 for specific application needs.

Overrides:

setContent in class ImplCode128

Parameters:

content - the content to be encoded in the Code 128 B barcode

autoComplete - has no function in this method implementation

appendOptionalChecksum - has no function, as Code 128 B uses a fixed internal checksum which is not optional

Throws:

BarcodeException - if the content is empty, or contains characters outside ASCII range 32-127
