public abstract class EAN128Builder
extends Object

abstract class for building EAN 128 barcodes, you should use a renderer specific implementation

Author:

Joachim Van der Auwera

Field Summary

protected String	codeA
protected String	codeB
protected String	codeC
protected String	fnc1 following members and methods should be made concrete by the implementing class as they are dependent on the barcode renderer (most printers need different encodings They should allow all types of renderers
protected String	shift
protected String	start

Constructor Summary

EAN128Builder()

Method Summary

String	build(Map<String,String> data) build the barcode data string
String	buildLabel(Map<String,String> data) build the human readable representation for a barcode which is normally used as label under the barcode itself
protected abstract String	preprocess(String data) preproces should handle any manipulations to the values which are put in the barcode to prevent any unintended special characters from appearing in the barcode.

public EAN128Builder()

Method Detail

build

public String build(Map<String,String> data)
             throws EAN128InvalidData

build the barcode data string

Parameters:

data - map with AI/value pairs

Returns:

string with barcode which can be interpretted by the renderer

Throws:

EAN128InvalidData - invalid barcode data

buildLabel

public String buildLabel(Map<String,String> data)
                  throws EAN128InvalidData

build the human readable representation for a barcode which is normally used as label under the barcode itself

Parameters:

data - map with AI/value pairs

Returns:

readable representation of barcode

Throws:

EAN128InvalidData - invalid barcode structure

preprocess

protected abstract String preprocess(String data)

preproces should handle any manipulations to the values which are put in the barcode to prevent any unintended special characters from appearing in the barcode. This will typically mean doubling escape characters or converting some characters.

Parameters:

data - data to preproces

Returns:

result after preprocessing
