直接已知子类:

UCCEAN128Barcode

public class Code128Barcode
extends BarcodeImpl

This is a concrete implementation of the Code 128 barcode. It fully supports all three available character sets (A, B and C), and also fully supports code shifts and set changes on-the-fly, providing an automatic optimisation mode.
